OT HEEEELP MY @#*%& COMPUTER IS *$&%%&

I used Litestep several years ago, and now use a bb4win fork called bbLean. Well, I found LS is a way too geekish. It requires quite a lot of time to tune it up and grasp the config files. And the main problem is that each theme utilizes its own set of plugins (typically) so you will have to configure it again and again if you change themes frequently. bb4win is free of this problem, because its theme is actually a color scheme. With LS you can create a feature-rich enviroment (huge amount of plugins) with as many bells and whistles as you wish. bb4win has less plugins and wherefore functionality, and targeted to create a minimalistic enviroment, which is still comfortable and easy to use.
LS is much more powefull undoubtly, because it can simulate blackbox easily (but bb4win can't simulate LS) but also consumes much more resources (21 Mb for LS against 2,5 Mb for bb4win on my system).
I'd suggest you to try both, because the approach is quite different.
