I've been looking around at bikes and I've heard that different forks can have a "really dramatic affect" on the feel. I understand that they have different travel lengths and require different weights to depress the same amount etc, but what are the biggest makers of front forks, in order from highest quality to lowest quality?

I'm talking like RST, Manitou, RockShox, etc

Thanks

PS - specifically, how much difference would you feel between the fork on a Trek 3900 (RST Gila T7 w/preload, 80mm) and one on a higher model (RockShox Dart 1 w/preload, 100mm). Besides the difference in travel, of course :0
