Writing this on my Librem 5 as a happy Librem 5 user, I struggle to find a good answer - maybe the Shift 6mq is an alternative (see the discussion on that in the equivalent to this thread in c/linux), as Shift have actively supported mainline development. The PinePhone is slower than the Librem 5, and the PinePhone Pro ... I could not daily drive it, too many bugs and too short active use battery life. If you just don't want to rely Purism shipping soon, you can always try a second hand Librem 5. Also: While I am quite happy, I am an enthusiast - YMMV.
