I guess I have at least two or three of "all the above." I've never had a problem with a plastic bucket, scratches and bacteria. Don't know that it couldn't happen, but I try to clean well and always soak with iodophor on brew day (or bleach or whatever). I did break a glass carboy years ago and despite protests, SWMBO took me in for stitches. She was probably right. I still have and use glass, but very carefully because I own them. Kids are no longer an issue. They scare me enough with teenager antics. I do have a BB, too. It's great.
In short, I go to the buckets first. Light weight, easy to clean and they have a handle. If I use a secondary I go glass. Not often.
