PC Tech Journal's VGA compatibility test suite is still available online from various BBS dumps, but the magazine itself also had a couple of in-depth articles where they sic it on a bunch of contemporary VGA boards.
Thought this was an interesting read:

1. Part 1 - Nov '88: https://archive.org/details/PC_Tech_Journal_v … ge/n49/mode/2up
   Covers the first boards from IBM and Compaq (where we learn that even IBM's ISA VGA isn't 100% VGA-compatible!)
    
2. Part 2- Jan '89: https://archive.org/details/PC_Tech_Journal_v … ge/n75/mode/2up
   Covers seven additional boards: Allstar Peacock, Tecmar VGA/AD, AST VGA Plus, Video Seven V-RAM VGA, HP D1180A, Paradise VGA, Tatung VGA.
