IME there are sort of two kinds of people here. People who are "fans" and defend "their" toy and people who don't. For example, I've been using Python for a very long time. I'm a "Senior Python Developer" so to speak. I quite like it for various purposes, but I can also talk your ear off about problems with Python.

I'd say if you run into someone who says they're experienced with X or love X etc., but they can't give criticism of it, they're most likely either not that experienced with X, or fanboys.
