Genuinely. The only thing I've ever noticed as a stand-out-it-bothers-me thing with a decent TN is vertical viewing angle.
The Samsung 204B I use every day has all the brilliance and clarity I could wish for, but the vertical viewing angle is poor. No escaping that. On the other side though, I don't disco dance when I'm in front of the screen so it doesn't bother me. But I'd be lying if I said it wasn't there and have found it common in most TN's I encounter.
