If you were to buy a new phone today, which one would you choose and with which rom?

Personally a big fan of the pixel series. Running a P7P unlocked right now. Google doesn't attempt to hamper the bootloader unlocking process in the least. I pre-ordered this phone and had it rooted on day one. I run stock (other than root) but I've played around with some others, like graphene and lineage.

One downside is that TWRP doesn't support tensor yet, so P6 & P7 aren't supported, but flashing is still easy without it.

Pixels seem to have a very long community support, I gave my sister an old P2XL with pixel experience on it so she had the latest security patches and she seems to really like it.

I've seen complaints about the P7 series overheating. I've had mine shutdown twice because of thermals, but this was in the sun while I was running nav on Android Auto. Moving it to the shade and letting it reboot seemed to fix that.

All of the pixels released so far don't have DP Alt mode which is a real bummer, but I've seen rumors that the P8 (October 23?) Will include it, so I remain hopeful.

For budget I'd always go with the current Pixel A-series

I am not that happy with my pixel 6 tho. I paid a lot and now like a year and a half after j bought I already look forward to replacing it.

I think my next phone will either be a Fairphone or a Asus ZenFone if they continue their current, amazing trend

You cannot expect us doing your work and research, also what has this to do with F-Droid, nothing. Choose the Rom you like and lookup which phone model is compatible, how hard can that be...

Any phone that supports DivestOS, and as a second choice LineageOS.

I will still prefer my SIM on a Huawei Kirin device rather than on a Snapdragon device though, and if needed will route my data and run the custom ROM device from the Huawei phone's hotspot.
