MIUI is garbage, just like any Chinese software. It's the most bloated mobile OS I've ever used. WiFi tethering got broken after some update, which is ridiculous. Bluetooth tethering never worked at all. Memory leaks are so bad you can't keep two apps in background after 5-7 days of uptime. And that's with 3gb of RAM. They even had to add some swap space to make it usable, but at least you can turn it off, which is called "Memory optimization" for some reason. Plus, you have to register a MIUI account to turn on developer settings. I'm not even talking about silly UI bugs. Basically any non-stock ROM is better

I haven't experienced any of the memory issues you describe. I have heard complaints about memory utilisation in previous versions of Miui, but I haven't seen evidence of major leaks.

You don't have to register a Miui account to turn on developer options - you just tap "Miui version" in the "about phone" dialog seven times. It's a slightly eccentric UI decision, but I understand that it's intended to protect naive users against shooting themselves in the foot. You do need to register a Miui account to unlock the bootloader and install a custom ROM, which isn't an entirely unreasonable security measure.
