GDE with the obsidian theme for me, I like the quirky screen transitions, the always there call and contacts buttons the don't impede on the homescreens, the communication history widget, and the application docks. It also seems to run the fastest and most stable on my droid.
That being said, I would love to rip the ability to hide the notification bar from home++, and the built in home++ taskkiller seems to work better than any of the standalone apps available right now.
Use bettercut on top of anything to change my icons (though if somebody could show me how to have a custom folder icon...) and it's pretty cool.
Sweeterhome has a ton of potential, but I'm nuerotic when it comes to changing things up, and changing anything SW is a huge chore that I just don't have patience for. Unless I just don't know how to make it easy....tell me Joe, am I just a moron?
