Apart from him saying that his drawing skills aren't that great (which was the exact point above, it's better to be slightly above average in multiple domains than trying to be the best in one, which is almost impossible), I disagree with you that the mentioned comic artists don't have drawing skills. XKCD looks simple, but the recognizability of these simple characters isn't that easy to achieve.
