I was using Home++, then tried Sweeter Home Beta 2, then went to HelixLauncher, and am now on LauncherPro.
Home++ was good, except that you can't change the dock buttons. It also is not compatible with Live Wallpapers (at least not when I was using it). And it force closed on me about twice a day.
Sweeter Home Beta 2 was awesome, but I just couldn't figure out how to properly customize it. It has a very steep learning curve and with working a full time 40-50 hours a week, owning my own business, and going to school full time, I just didn't have the time to learn how to customize it.
HelixLauncher is an awesome launcher. Customizable dock, Live Wallpapers, speed, and many more features made it a really good launcher. However, LauncherPro is better (IMO).
LauncherPro is the best launcher I have found. It is extremely fast, very customizable, compatible with Live Wallpapers, has a customizable dock (you can even change the icon to whatever you want), and has never force closed on me.
With all that said, when I finally get 2.2 I will try the stock launcher, but have a feeling that it just will not stand up to LauncherPro. So, to answer your question, I will probably end up using LauncherPro instead of the stock launcher.
