Well, I don't mean to say that Willamette is gross in all applications, I don't care for it, but lots of professional breweries use it (because it's cheap) It's derived from Fuggle, which I think has a superior flavor profile. Taste is all relative of course,
FT uses Willamette, Goldings and Target. Target is a high alpha bittering hop, Goldings and Willamette are moderate alpha flavor hops. I'd use Goldings, or Styrian Goldings, Fuggles, maybe Glacier. It all depends on what character you want, every hop is a little different. Goldings, Styrian Goldings, and Saaz are classic in anything Belgian inspired, these hops are expensive for pro brewers to use, but in our quantities it's only like a dollar more so it's worth it.
Glacier is a good generic hop for beers that don't need a strong hop character, clean bittering, kind of round, slightly fruity and inoffensive.
