Games like Megaman 8, and all SNK and Capcom fighters are better on the Saturn than the PS1. Mostly they are improved in graphics and performance. I bought my Blue Derby Skeletal JP Saturn new for $200 back in 2000 with a ST Key cart. At the time I got it mainly for Dragon Force and Guardian Heroes. Worth owning it just for those two games. Later on I bought Assault Suit Leynos, both X-men/Marvel vs Street Fighter, Vampire Savior, and a few others.
When I got back into playing my Saturn again in 2006, the prices were too high for some games I wanted to play. So, I got a US black round button model Saturn and installed a mod chip to play CD-Rs, lol. Yeah, I know it looks bad, but I refuse to pay those prices for games like Panzer Dragoon Saga, Radiant Silvergun, Hyper Duel, etc....
