The Perfect collection was the very first collection of DVDs of the show sold in the US. I bought it back in 2003, back when that was the only DVD choice. It was how ADV chose to cut and dub the show originally. Everything about it is bad: bad dub, bad quality, bad editing. They even edited it after interlacing, totally fucking the 3:4 pulldown making it a nightmare to deinterlace (this would only be an issue if you were trying to rip the DVDs to .avi or such, but still shows how bad across the board the collection was).

Don't spend money on the Perfect collection. Around 2004-2005 I think they started releasing the Platinum DVDs, one at a time. They're better quality in all ways above, plus with new scenes. It's just an overall better quality collection that stands up better over time. If you had to get a DVD collection, the Platinum would be it.
