There was always something about Dreamcast games... I just can't put my finger or it, or know how to describe it. I think it's because it's such a "Y2K" console, you know?
I mean, the Sonic Adventure games on the GameCube were fine given they were upgraded ports. But the Dreamcast provided that resolution, that tone in graphics that GameCube, PlayStation 2 and XBox didn't quite have at the time. I wish I can put to words what made any game presented on the Dreamcast had that unique quality to it than the same game presented on the other consoles at the time.

Because in texture and clarity, NAOMI is better than PS2 and Game Cube though of course it loses in term of raw processing power.
NAOMI features hardware texture compression and a more flexible Video RAM setup.
NAOMI also natively supports 480p progressive scan via VGA, delivering a sharp, clean image.
The vast majority of PS2 games run in 480i interlaced video, which causes flicker and jagged edges (jaggies) unless a game explicitly supports a 480p mode.
Of course there are other factors like how good the team who handled the port and their time constraint.
If the port was handled by a good team and they have enough time, the port is still perfect though like Capcom vs SNK :
