NESDEV is a homebrew forum where quite a bit of technical discussions happen, and most participating know what they're talking about. Think of it as an NES centric version of the spritesmind forums.
The Saturn versions of what exactly? Street Fighter 2? As we know it can't do compressed samples so that probably hurts the voice and sound effect quality. However Capcom took an extremely lazy route with both the Saturn and PS1 ports of Street Fighter II and Super Street Fighter II. They used CD Audio. As a result there's a slight pause between the main track and the low health variant due to CD seeking time. Also the tracks don't loop. While this is rarely an issue as a match should end before this, if it goes long it will happen. And in Super Street Fighter II it's more prone to happen since the music from round one continues playing into round 2.
Which reminds me, that is one area where Super Street Fighter II's audio is better than the SNES. The music from Round 1 continues playing into Round 2 just like the arcade. Meanwhile on the SNES it stops and restarts in between each round.
