I have both phones (but already sold my Nothing Phone 1 after 1 month of using it). I do not see any issue with MIUI, in fact it really suits me well (in term of speed and efficiency). Those bad things about MIUI like pre-installed app can be easily removed with just 2 clicks. Just need 1st time tweak to get rid off those built in 'recommendation' aka ads. I do not want to argue MIUI vs other skins/firmware, as it is up to each individuals preference. I tried below phone to replace my Mi10T:
1. S20 FE
2. Moto Edge 30 Pro
3. Moto Edge 30
4. Nothing P1

I think I will use this 12T longer, as I believe I already comfortable with MIUI and its ecosystem. In fact, i will keep my 10T for spare phone, not going to sell it.

Again, it is your choice. Just use whatever phone that you think you're comfortable with.

Just bought a 8/256 12t pro for under 2.5k.
Good price for the specs!

So sorry, under 2550. Still want the link?

It's a13. So far most brand flagship or sub flagship already updated to a13. Apparently for flagship model, only moto x30 pro/edge 30 ultra still under a12 but that device is not officially available in Malaysia so doesn't really matter.

I am no expert. I didn't own a single moto device. Better u go to moto thread and ask there.

Since you asked, I help you to google and this is the result. This is what I found online so I have no idea is it correct info or not 😂

The best person to get info is moto sub threat in this forum
