If you keep green bottles in the dark, they are fine. I have about 3 cases of green 750's that stay in the cellar in wine cases and age just fine with no skunk.
Stella IS a great beer! I think its awesome on draft, but most bottles I've had are vile. I did have a funny story of a co-worker saying "Man Belgian beers are awesome...I don't think I've ever had anything better than Stella in my life!"
Have to disagree on Moretti, that stuff tastes like rotten meat to me (though it may also be a packaging/age/shelf stability issue, as I had one on draft in Florence and it was great).
What funk characteristic do you get from green bottles? Is it actually the 3-MBT/skunk? I like saisons with a little funk, but not with skunk....
