ProtonDB now has separate tabs for easier browsing of Steam Deck or PC reports. You can also view a combined tab that includes reports from both.
Both categories can be pretty useful, but some game fixes can only be found in the PC section. A lot of the PC report creators are more experienced Linux users and know of fixes that may not show up in the Steam Deck section.
Finally, I have been so tired of having to scroll to the bottom of every game’s page to find entries relevant to my hardware.
