The Sega version works well as bgm and I'm very glad that we got another version of the soundtrack. It was recorded/mixed/whatever with a heavier/more modern sound, but the actual performance loses a lot, seperate from the style changes.
But the one thing that really kills the Sega soundtrack is the redone solos. Its not just that they're not as good, they really don't fit the songs and feel very out of place, almost working against the music.
