Yeah, I have tried all kinds of launchers like Launcher Pro, vLauncher, ADW, Zeam, and maybe a few others. I have a Samsung Fascinate, and I've always hated Touch Wiz. This is why I've tried so many. Lol.
Launcher Pro has been my favorite for a while. A basic design for an android phone's UI. Seemless, and zippy. It's definitely a must-have.
vLauncher was a very basic approach. It was almost identical to the iPhone's UI. You couldn't have widgets on the screen which was good for me because widgets are good at sucking the life out of my battery. But there is no app drawer. Your phone's screens ARE the app drawers. And I highly suggest using folders. I even had a folder named "Useless" for all of the bloatware apps I'll never use. Lol.
ADW is just terrible. Lol. I didn't like ADW at all. There's not much to say about this one because I didn't use this one much at all.
Zeam was a whole lot like launcher pro. Just a different kind of dock. I didn't use it long enough to really like it. It definitely looked a lot "Shinier" if you guys kinda know what I mean.
I tried all of these out and decided, "Hey, I'll try using Touch Wiz again." and then I did, and fell in love with it somehow. I'm Planning on sticking with touch wiz for a while.
I can honestly say that Touch Wiz and Launcher Pro are the only two I will really use. If you're rocking a Galaxy S phone, you may want to change the Home Launcher. Unless you want to keep the original Galaxy S-ness with the Touch Wiz and be cool like me.
Still Waiting for Froyo though. :/
