i'm not saying it never works or crashes all the time, but i've seen big fedora crashes and there are some well known big bugs
check that one out :
Windows sidelined by Fedora bug - ZDNet UK
but if you used redhat free version, most people were really dissapointed with fedora, redhat free was rock solid, stable like rhel, fedora was much different, and frankly really not that great, i had multiple crashes on FC7 using vmware (not exactly a hard platform to support...)
I'm dissapointed at redhat's strategy but then centos came along and well in my opinion fedora has little reason to exist except as to serve as a public community beta of RHEL.
This really got on my nerves and I changed to Ubuntu now. I works great and so far I haven't had any bigger problems. It's even easier to use than Fedora and with compiz fusion it looks great too.
I just hope this doesn't change like it did with Fedora.
This is how my desktop looks now
