It's pretty obvious, Quake II still looks very good on a Voodoo2.
3DLabs Permedia 2
The Permedia 2 seems to lack of color a bit, making it look a little odd in the comparison. The corridors and the walls look pretty alright, the floor of the level seems a little bit chaotic in the background though.
Look at the comments made in the conclusion, both Nvidia and ATI are getting owned by 3DFX and even more owned by 3DFX's SLI technology. How times have changed, no more 3DFX, ATI actually produce decent video cards and games running at 1680x1050 rather then a 800x600.
