<p>I disagree, my favorite teacher so far in college has been a TA. I was much more comfortable talking to him than to any of my professors; he was an awesome teacher, and he knew his stuff. With the exception of their age and maybe their wardrobe (t-shirts and jeans as opposed to tweed coats with elbow patches) I doubt I would have been able to tell my TA's from my professors in terms of teaching ability. My TA's have, in general, been much friendlier, much more involved in the class, and my professors while good too, have seemed more aloof and more likely to lecture than discuss.</p>
