There's hudreds of threads discussions on here, at least one a week, asking the same question, but the answer is always the same. It's a matter of preference.
Very few people give any real credence to the whole glass vs plastic idiocy. Most of us laugh when we hear those arguments bandied about. It's usually from the extremely noobish, and/or unscrupulous (or just plain ignorant) LHBS people trying to pimp an expensive glass carboy to the unsuspecting, rather than a cheaper (and just as fine) better bottle or plastic bucket.
The yeast don't care what they do their job in....In reality a fermenter is a fermenter is a fermenter.....glass, plastic, carboy, bucket, jerry can, keg, milk jug, ceramic crock, glass hurricane jar, stainless steel or plastic conicals, pet food storage vessels (vittle vaults), HD or Lowe's buckets, frosting buckets, water jugs, the old Mr Beer jug...All of those and anything you can think of, all work perfectly fine, and have been used by hundreds if not thousands of brewers...
No one type is better or worse than any other...good beer or crappy beer can be made in all of them, dependant onthe brewer, NOT what it's fermented in...
