Can anyone recommend some android alternatives?

I'm not looking to move away from android permanently but I'm just curious, I enjoyed my time with UBports (fuck QT) and seeing projects like the PinePhone and Librem 3 just get me curious what is actually out there.

Currently rocking a pixel 2 XL but not shy on buying new hardware to test stuff out as long as it's within reason.

Currently had a look at PureOS (not available) and Sailfish, any others to give a whirl?

So I found my old phone and apparently there’s Sailfish OS for it

Has anyone here tried Sailfish OS? I'm actually pretty impressed by it. It feels like a true mobile version of Linux without all the privacy issues of Android (Google) and the freedom you don't get with iOS. I think it looks pretty great too.

If you have tried it, what do you think?
