I find that most of the tools on multitools don't get used that much. If I have a serious job to do, then I go to my tool box and get a real tool. The main advantage of multitools, IMO, is to be able to do a few simple tasks with what is on my belt. I use the pliers the most, followed by the screw drivers. I rarely use the knife blade, because I always have a better knife in my pocket.

I'm a keep it simple kind of guy. And as I get older, I find I like to keep things lighter weight. Since I rarely use most of the saws, files, scissors, etc on the more elaborate tools, those features are just excess weight to me. Therefore, the multi tool I keep handy, and use occaisionaly, is a simple one. I like the plain old basic Leatherman Kick.
