I have both the old glass and plastic versions. So far I've still had to draw samples as krausen residue blocks my view. I wish the glass version offered a dual port lid, a feature I like on the plastic.
One thing I don't like about the wide mouth on either is it doesn't fit on the keg washer, but it is still easy to clean.
The key to using glass is to always put the carry harness on it prior to filling. I still use carboys as well when needed.
