So far been to various ALL IT and Thundermatch has quite a few choices to test. For my case, last year I was in Tokyo so I had the chance to go test all I wish in Akiba. Particularly, Yodobashi had nearly all the keyboard models on sale with demo units to test. That was how I used them to narrow down the type of switch I prefer.

If go by keeb reviews Aula is a very good budget keeb brand, their F75 seems super popular if your into that size.

If your looking for budget 100% full size keeb, can consider Thunderobot K104S. Here is my review of higher end version https://forum.lowyat.net/topic/5526067

Purely for office you can get lower end version (all black, soldered switches, less RGB function). Its also a bit cheaper

i'm quite satisfied with my F99 Aula.

If you don't mind a plastic out casing for the mkb, it's fine. There is enough heft to it so it doesn't slide  around when typing. But there are alternatives if you insist on having a full aluminium other metal chasis for the mkb, but that will cost you extra.

Battery life last long time. Someone recommended me this over a different brand, but this had more battery life. Good thing i went with the recommendation. I use this for weeks on the battery using 2.4ghz wifi.

the lighting is ok, enough for me. lots of effects to choose from. for me i opted for the lighting where it only shows when i press stuff. this also helps saves battery while still having that bling.

the software UI and macro setup is sufficient. I don't have a comparison for that to other brands, but i read other brands do a much better job in terms of UI for the mkb software settings. I tried it and it's sufficient. To use the software you have to used the wired type c usb. Once done configuring, you can remove the wire and stick to wireless mode.

F99 is not a 100% layout. it's close to it. It's ok for 99.9% of the time, but since there is no print screen key, i had to repurpose via the macro to change one of the least used keys like pgup or pgdown to print screen. thats the main downside for not being a full 100% layout.

There is a different aula model that is a newer model and is a 100% layout, so i would recommend that over this F99 tbh.

The keycaps for this Aula F99, is very good especially at the price point i paid for this. Mine is the white / grey / black color scheme, a very techie classic retro look. other people may prefer more modern color schemes.

the switches that came with this model i'm satisfied with. actuating the keys don't feel too stiff, they are silent (as it gets for mkb switches. probably not the most quietest but not the worse either. but for me it was fine. And it's not clicky which i hate.)

cleaning was easy. take a picture, then pluck keycaps with keycap puller, toss them into a bucket with cleaning fluid and let it soak a while then later rinse and dry them (ideally under sun). any dirt stuck inside the casing just use a hand held blower to blow it out.
It doesn't support VIA or QMK firmware if you like those modifications for the software. The software features for me was sufficient. I only worry the most whether the mkb had a keylogger or not (since its a china brand). probably doesn't    *cross fingers
