No one except the OP will want to hear my opinions on glass vs. plastic.
Yes, glass is dangerous, and you need to be very careful with it. However, plastics *can* at times harbor wild yeast and bacteria that can give your beers a "house flavor" that glass will not do. Plastics are also oxygen permeable and for any long term aging, you can taste the effects of oxidation. If always doing quick batches, this is less likely, but if keeping in there for a couple of months, you might pick up premature oxidized flavors.
There are certainly advantages and disadvantages of each. Personally, I am interested in making the best beer possible. As such, I use only glass. For me, glass is worth the risks, and I am very careful with it. I suppose at some point I could even seek out stainless steel carboys, as that would work even better, albeit you cannot see through the sides of stainless obviously, so that's a downside of that.
We all need to make up our own minds and do what we think is best for us and the risks we want to take.
I haven't read all the other posts but just gonna say at this level there isn't going to be any difference in quality of beer between plastic and glass except for the instances where you are aging the beer long term. In that case I do agree glass is slightly superior but only slightly. If you think there is no ingress on the rubber bunch and air lock on glass carboys you haven't really thought this through.
Glass fermenter use is limited to sours for me.
