So yeah, not flagship but close enough for a lot of people (side by side, the a32 vs s21, for me is not worth the 4x+ pricetag, as in the difference between flagship and not flagship is shrinking fast, ymmv), however...
The pinephone is worse hardware though (In almost all respects but the dipswitches) and the software, at this point, is really alpha quality mostly. But we know this: the promise it will run Linux smoothly on a phone is enough to buy one. It will take time but I would buy any phone that allows me to freely run multiple OSs new out of the box with all hardware supported.
According to https://wiki.postmarketos.org/wiki/Devices - that's a rather uncommon thing to have, and pretty much unobtainable for a recent device (other than pine64/librem5).
