Extreme?

i know alot of people on here dont like Extremes. i was just wondering why. is it because of the fact that they cannot go very low because of the kit. because right now im in the process of finding a new truck. and i really want an s10 ext cab. 2wd so i can lower it. but the one problem im having is deciding what to get, a regualar s10 or an extreme. and should i get a 2.2 or a 4.3. i cannot find an auto 4.3 anywhere.
