L8wrtr's versions would be a pretty solid choice, with a mass of consensus behind them that cement them in place as many people's adopted versions. I consider L8wrtr's versions to be roughly the full realization of the Phantom Editor's philosophy that got this whole ball rolling to begin with.
Q2's edits contain systemic deeper cuts, which IMHO weaken the films overall (even as I agree that what was cut often deserved to be cut). For example, in his version of Episode I R2-D2 flys into battle and destroys the ship on his own, while Anakin stays on the ground. To me, that's a bit farfetched from a storytelling point of view. However, Q2's versions are good choices if you want prequel edits that set out to function as someone's first introduction into Star Wars in chronological order, attempting not to ruin plot surprises in the OT.
Seciors is working on the PT as a whole, though the only HD release so far is Episode I. His edit works very well as a first-time-viewer's introduction to Star Wars in chronological order, moreso that Q2. For example, he does not depict Sidious directly, contriving it into a surprise reveal later. His versions, therefore in my mind, do not work as well as others if the audience is already familiar with the OT. As said above, watching Seciors' Episode I and L8wrtr's Episodes II and III would be sensible, if you like.
And of course, there's my own prequel trilogy edits too. I have said before that I felt like more of a curator than an editor at times, since there were so many edits already extant. My philosophy, like L8wrtr above, is that the prequels are prequels, and one should have seen the OT beforehand.
So, my recommendation would be to check out either L8wrtr's edits or my edits if you prefer to see the OT before the PT, or to check out Seciors and/or Q2's edits if you prefer the films chronologically. (Though I don't think you could comfortably mix and match between Seciors and Q2 because Q2's edits pretend that R2 and 3PO are different droids.)
