I was thinking about using graphene OS, but I've read some lemmy users dislike this OS due to perceived misleading advertising and the pixel 7a you're supposed to install graphene on because it's from google (an advertising company).
Another option would be lineage OS, but there is so much false information about this OS, namely compatible phones that simply don't work with this OS and no support.
what works for you? I want a phone with no google, that doesn't force me to use the manufacturer's ecosystem and that won't show the apps I don't want or need (on an asus I own you cannot neither get rid nor hide bloatware)
It really depends on what you want from your phone and what matters to you.
I recently got a refurbished OnePlus 9 and put lineage on it. I would have gone with a pixel and graphene, but pixels with more storage are hard to come by and expensive.
Find which roms are available for your phone and choose from there, or if you want to change the Asus phone, look at your target specs and which phone ROM combination you can find
