I haven't programmed Flash in my life, but I can't say I've had Flash crash on me more often than, say, once a few months. Definitely not often enough that I notice it as a major annoyance, on either Mac or Windows.
Now, Flash is annoying for other reasons, but crashing isn't one -- for me.
(offer an anecdote, receive an anecdote.)
I've never had my browser crash on me either. Firefox-user on Windows here. To me Chrome seems to "fix" a problem I've never, ever had.
Oh, that's one more plus for switching to Chrome browser I hadn't realised (I've been using Chrome for a few days exclusively; I do web dev so this is a big thing).
