My first Android was Redmi 2.. and then upgrade tk Huawei, but then i went back to MIUI RN4..now im on S7e but not really liking it.. kinda have soft spot for MIUI.. is stock Android really gooding?

Hey guys, currently looking to replace my current phone (S7e) which im not really comfy with..

I've used Redmi 2 & Redmi Note 4 before this and thinking to buy RN4 back again because miui feels so familiar with me

However kinda interested with Mi A1 particularly because of its dual camera and usb-c port (can share cable with my wife S8) ... but my concern is the stock android..is it good? Any drawbacks tha using miui? Because im confortable with miui before and even samsung ui also im not really comfortable with..

Mi5x use global rom?

I think not comfy with the phone itself haha.. maybe knowing that this phone screen gonna cost rm1.2k to replace
i never use tempered glass on RN4..
i can sell this phone, buy RN4 and still have balance to pay my postpaid bills for 3 months lol
because most of the things that i am doing now with S7e, can be done by RN4 just as good.. im not a gamer summore..
the only thing that is really good about S7e i think is the camera

When I used Redmi 2 and Redmi Note 4 before, both phone GPS sucks all the time. But when I brought RN4 to the US and use it for navigation there OK pulak never had problem
