Just in the Orange Pi lineup, there are so many different models and so little structured information about them, that the best source still seems to be the google sheet that I created in 2017 and has been continously updated by various community members over the years [0]. And that's all one manufacturer!
Things like which type and how many video outs, USB ports, if it has onboard flash, DSI/CSI, pinout compatibility... are so much more important and so much harder to get than performance numbers, which usually boil down to the SoC plus a small margin for thermal and power design of the board.
If this site were open source (and time + knowledge of stack permitting), I'd take a stab at adding a way to include that info as well, maybe even through crowd-sourcing.
