Android Box 101 You probably know what is an Android Box. If not, its just a TV gadget running Linux kernel/Android OS. You install apps to play local or stream online contents. These are some basics to consider...
Android OSGet Android 5.1 or higher. Android 4.4 is just too old.
Some boxes come with Android TV (Nvidia Shield, Mi Box International, Nexus TV), MIUI TV/GITV (Mi Box 3C/3S), Mango TV (Himedia HK/China). These TV OS are based on Android, and are TV remote friendly. You will not get full Play Store with Android TV. MIUI/Mango TV is for China which ban Google, and is somewhat troublesome to install Play Store. If you need Google, easier to get something else.

Android 4 - Too old...coming to end of life, I would skip.
Android 5 - Well supported, 2-3 years more life...
Android 6 - Most current boxes comes with this, some app compatibility issues reported but I would expect these to be solved by responsible developers...otherwise beware.
Android 7 - Very new. Only Himedia Q10 Pro/Q5 Pro running it for now, but cheaper boxes are starting to show up with it.
Google TV - A short-lived product. This "evolved" to Android TV.
Android TV 6 - This is designed for android box and TV type remote control. Play Store will push only TV/remote friendly apps only. Google is driving this for a unified and consistent TV experience, so this is really good for folks who wants a lower maintenance easy to use experience. The Shield and Mi Box US/International/Malaysia model runs this >>>
http://www.mi.com/en/mibox/ PS: The Mi Box US/Intl has the same hardware spec as the Mi Box 3S for the China market. Don't buy the wrong one.
MIUI TV - The Xiaomi's TV box for the China market. NO PRELOADED PLAY STORE, AND VERY DIFFICULT TO INSTALL.
Mango TV - The Himedia launcher for their China boxes. You may find some semi-official ROMs with Google Play.
Jailbreak/RootJailbreak is for Apple devices...while Root is for Android.
Jailbreak is freedom from Apple's control...Root is just write access rights to its root folder...
Rooting is not required for the box to work as a TV box, or to install TV apps. Some apps will not work after rooting.
RAM/ROMI recommend 2GB RAM, 16GB ROM. 1GB RAM makes UI response slower, and could lead to buffering, depending on box/app. 8GB ROM is barely sufficient, after Kodi and a few apps you get about 1GB left. The box you like is only 8GB? Don't sweat it, just get it and manage your apk carefully. You can of course get more.

1GB RAM - Too little nowadays, box will be sluggish, UI experience sucks.
2GB RAM - Just nice for now. You're not really multi-tasking and need more you know...
3GB RAM - Some future proofing if desired...
4GB RAM - Latest RK3399 SoC boxes comes with it, these are more like NUC/Chromebox alternative desktop
4GB ROM - Too little. OK if you don't install Kodi. (The HyppTV box has more!)
8GB ROM - If you know what you want. After Kodi, addons and apps, you get maybe 1GB left...
16GB ROM - Get this as basic.
32GB ROM - If you need/want to store media onboard.
64GB ROM - well..
System on Chip (SoC)Amlogic S905, S905X, S912 are the most common. Others from Rockchip, Mediatek, Hisilicon, Allwinner, etc. They all work, the top flagships are obviously better. Right now Kodi with V17 is taking a hard-line approach with non-Google standard firmware by chip makers, hence some chips perform better than others with audio pass through & down mix.

Some current chips:
S805 - Old slower chip. I would pass.
S812 - Old fast chip. Still good if you don't need all types of 4k hardware decoding.
S905 - An older well supported chip.
S905X - Most new boxes comes with this. Get this if you need/want VP9 hardware decoding and HDR/Hi10p.
S912 - Most new boxes comes with this. Get this if you also want to try 3rd party Superceleron ROM...just make sure you get the right board.
RK9229 - New low end slow chip. I would pass.
RK3188 - Old chip. Pass.
RK3288 - Old fast chip, not very common.
RK3328 - New chip, mostly running Android 7.1.
RK3399 - New fast chip. Quite expensive boxes.
DolbyIf surround audio and video quality is critical, on-chip Dolby processing or licensed firmware is required. Everyone claims full support for pass-through and down-mix, but only a few does this well. Most other cheap boxes rely on software decoding and it can be a hit or miss.

Dolby Vision - such Himedia Q10/Q5 pro have this.
Dolby / HD Sound - such as Minix X8-H, and U9-H, as well as the Himedias above, and some Wetek.
Amlogic chips with "-H" postfix, eg., S905-H, means they have on-chip Dolby audio processing...audio pass-through & down-mix will be better handled.
Miracast/ChromecastMirracast - To stream from phone to box, phone is active sending data from phone to the box. Most box will have this.
Chromecast - To stream from internet to box, phone act as controller to set up the internet-to-box streaming connection. Only Chromecast certified boxes have this.
Box I/OStandard are HDMI, USB, 3.5mm AV jack, remote control. A wired/wireless/air mouse is a must have IMHO. Other connections that may be important:

LAN - More reliable than wifi
S/PDIF - For external DAC or AV amp
RCA (red/white) – For stereo amp, AV amp or old TV
Video (yellow) – For old TV
Headphone – You use it like Android PC, or to PC speakers
Mic – You use it like Android PC
Sata – For direct bare HDD connection
Memory card - SD, TF or none
OTG - as storage
On/Off switch - Can be important if it doesn't auto on
Wireless keyboard, wireless mouse, Bluetooth headsets, USB DAC, USB camera, USB microphone, etc., these mostly all work.
Wi-FiSome boxes comes with external antenna, these will likely give stronger wifi connection. Some are dual band. Some has ac in addition to b/g/n. These all add to the cost but improve functionality and user experience.
Codec SupportSome jargons you will see...VP9, HEVC, H.265, H.264, RMVB, HDR, CEC, HDCP, 10-bit, AC3, DTS, blah blah blah...
If you have 4K TV, 4K AVR, then HDR10 & HDMI 2.0 will be important, but most box support anyways.
Most box claims they play everything...but it doesn't claim flawless playback. Check reviews to confirm. Most streaming formats are geared for widespread distribution, backwards compatibility and hence easy to decode...so don't worry about this too much. Just be aware sometime some old oddball file or two may be encoded strangely and can't be played well on any box except the PC...
