I haven't either, actually, other than a chapter or two in scanlation when I wanted to compare something specific in the translations. I just find the Viz version kinda clunky (I think it's obvious that it's one of their older titles), and miss the name honorifics. My impression is also that it was rewritten more heavily than I'd like. And it's flipped. And so on. :/ It's adequate, but I wish they'd done better.
