I use plastic containers for measuring, mixing, storage, film development and for prints too. I have never dropped any of them (in more than thirty years, but I have now jinxed myself...) but bits and pieces of gear do get carted around when travelling and glass could be a problem in those circumstances.

Someone mentioned a five-litre beaker - I am probably horribly cheap, but for mixing large amounts of Bromophen and so on I just use a bucket (which doesn't get used for anything else) and then measure what goes in to it, instead of what is in it.
