Wow, another Darwin thread? Oh boy. I might give the Darwin another chance if, 1, it wasn't so damn ugly, and 2, it didn't have the side mounted atomizer connection. The integrated battery is another part I'm not fond of, but I can live with it.
Right now, the ProVari is tops in my book. It is versatile, flexible and has a great look. The new colored version will be even nicer.
The Eclipse has a lot of promise. I just hope it lives up to the hype. If the feed system really works with the mini piezoelectric pump and all of the other features promised deliver in a sleek package, that will certainly be a contender for title of "most badass".
The Darwin, IMO, falls far short of that mark.
