WH have a bit better/powerfull finishers then WE, but overall it's pretty much the same. I'd say that you have to try em out, as the classes are pretty much the same and the differences is small abilities, that yu spec for later. I main a WE and absolutely love it, but for some reason I think WH is oe of the most boring classes in the game

Try it out, and see what suits you - after all lvl cap is only 26 atm, so it's not like, you're gonna loose days of work on nothing
