Not even close, I can't tell you the last time I've wasted a day trying to get something to "seemingly" work in IE that worked in firefox. Sometimes fixing it in one place would break the other. It was a nightmare where I'd loose hours maybe once a week. I just don't have those problems anymore. Maybe its because I was a junior dev back when IE5 and IE6 was everywhere... but I lost a lot of time on it.
Perhaps I should clarify -- I am (happily) not involved in web development, and from the developer's side browsers may very well be in pretty good shape these days (I wouldn't really know).
But speaking purely as a user, I think the statement "browsers suck, like really bad" still holds very true.
