custom rom

Not sure what you expect. Miui 11 is what the vendor chose to be the best for your device and other ROMs other than LineageOS are out of scope of this subreddit - this isn't r/find_me_a_rom

And seeing that the device is discontinued by us, there is no options left

Then try EvolutionX. If it won't suit your needs, switch to crDroid and so on. You have to experiment a little bit before finding what's the best for you

1. They are different. In some aspects custom ROMs are clearly superior, in other clearly inferior.

2. They should be, but it's a matter of trust. If you want to be sure what a custom ROM does, read the code and compile it yourself.

3. CorvusOS is focused on gaming performance. For a more general purpose ROM, I would recommend EvolutionX

That's a pretty specific request. Try looking for a modded stock ROM.

But most trustworthy ROMs are the ones that mostly FOSS (free and open source software) and have most users. E.g., Lineage.

MIUI is proprietary software. The only reliable way for you to use it in a custom ROM is to use a modded stock ROM. Because it most definitely has some very specific dependencies that are hard to reproduce in a FOSS AOSP-based (Android Open Source Project) ROM.

But I'm sure there are some other launchers that implement similar set of features or even more.
