I think it's perfectly fine. It's 5 neo geo games for 15 bucks - a total steal. The only real complaint anyone could possibly have against it is the oddball announcer glitch here and there and the lack of arranged tunes.
As to the saturn ones, go nuts, if you want to pay more money for versions with missing animation frames. May as well just get the Japanese Orochi collection (without 94 and 98) if you're going to import anything; closer to the arcade version for 95-97 than Saturn, and has arranged music.
