We had, just a few weeks ago, a contest b/w the master builds (legendary was not a category, at that time). Paul randomly paired the different builds, and the membership voted in the Character Build Shootout. Some of the individual round pairings have been edited out, but you can figure most of them out from the membership's comments.
To no one's suprise, it came down to builds between Ponty and Mason. You can find the results of all the voting here.
Mason's Alik'r is probably still my favorite. Mason's and Ponty's builds are always high on my list. In fact, all of the buids from the Character Shootout are wonderful. But ignoring the earlier Character Shootout builds, my choice from the newer builds would be 'The Berserker' by Cryptstalker - it is just simple and fun to play - everything just seems to fall into place.
The Orchish Impaler by Skillusionist is a 'front-line' archer and deserves a mention for introducing that concept.
