Framework's been transparent through the process about firmware issues being part of their mainboard development. A lot of their problems are specific to the intersection of their expansion slot/USB-C port capabilities, particularly power draw and PD/DP capabilities, and AMD's firmware for mainboard components. I'm not surprised that GPDs have a more solid experience as they're not expected to be as flexible.

And I want to emphasize that the "support" as in Framework responding to and shipping fixes has been good. The "support" as in the hardware working consistently, particularly in Linux and without distro-specific workarounds, has had holes which sound common enough outside of Framework devices that I'd wager the GPDs are the exception more than the rule.

I'll say at least that the Framework's fingerprint reader and display settings Just Worked through the upgrade.
