I started playing drums 30 years ago on acoustic kits, of course and now I'm an owner of a Td-11KV and I feel good with it. The most noticeable differences are the increased rebound of the mesh heads and the source of the sound as you mentioned. The higher rebound is a good thing in my opinion but the lack of "acoustic vibrations" isn't that cool.
Another lack of the TD-11 module are its default sounds: that's why I realized my personal setting trying to get better sounding kits. You can find some example and some free kit on my site: http://pieropeluche.yolasite.com/pp-drums-freebies.php
