In terms of environmental and character detail, there's no getting around that the cube is easily superior. Much higher geometry capabilities (except for particles) and texture details because of flippers tev units and extra memory. Certain multiplats may have seen a higher res texture on the ps2 because of its larger main memory, and wasn't reworked for the cube's memory set up. In terms of playing the games on CRT, image quality isn't a big divide but a lot of games on PS2 are interlaced or use strange resolution tricks that don't hold up at all on lcd where as gamecube holds up well provided it's not a huge screen. I keep a crt around just for ps2 and n64.
