I have the paperback copy. I haven't stress tested it but I've had it since probably 2013 and it's still intact. The pages are on the thinner side.
The fact that it's still intact after 10 years is a good sign.
I should check how many of the stories I already have via other publications.
ISFDB is my friend for that sort of query (edited to link directly to paperback edition with list of stories therein):
