Personally, I prefer "Aerowalk [Hubster's Remix II] by The Preacher - conversion by the Hubster" - lvlworld.com/review.php - even if the title of the re-worked version is ridiculously long :]
But, yes, starting up a QuakeWorld server at a LAN playing the original is by far the best way to play Aerowalk.
Nothing can beat the original since it's just an original. Making the same type of map but with Quake 2 textures really doesn't make a difference at all although this does actually look very similar.
With the exception of the wind tunnel/jump pad, and the alcove destination by the grenade launcher instead of a fall to the grenade launcher, I would have to say, this map is definitely awesome. I don't think Tiger reviewed this one properly =P
