I like L8wrtr's best overall, although I wouldn't necessarily call them definitive.

HAL's are a bit more lenient on pacing and a bit less aggressive with cutting.

I personally still like Kerr's episode III the best although it's only available as a SD DVD.

Q2's I would only try if you want the OT "secrets" preserved although that's never interested me.

Seciors Episode I is interesting (I haven't watched it front to back but it does some bold things), his Episode II doesn't really work for me at all however.
