Update on my trials: Thought Launcher Pro was so sweet I didn't even want to try anything else.. but yesterday I was having a problem getting my HDMI output to work and mistakenly thought it might have been due to the launcher (actually it was because I froze the webtop apps with Titanium backup, D'oh! fixed it though).. so I uninstalled it, and when I fixed everything I figured it was a good enough time to give another launcher a try.
Now using Go Launcher.. gotta say I do really like it. Probably the only thing I liked better about LP was the app drawer - it looked prettier and loaded maybe a few milliseconds quicker, smoother and prettier looking effects-wise with LP -- though it RUNS equally smoothly and I like that I can still view all apps in the vertical scrolling view.
GL's homescreen options are superior, IMO. I like how ridiculously easy they make it for you to add/remove and manipulate your homescreens. I only use 3 (minimalist) now but I like that if I want to change their order or add more or get rid of one I can do it in literally like a second. Just been toying with the gestures available but I am liking those too.
GL does work nicely with resizing widgets -- something LP wouldn't do unless I bought the paid version. And the Go Calendar widget, as DBox pointed out, is definitely really, really nice and useful. I like that a lot.
Still going to experiment with some of the optional add ons and themes for GL. Overall I do prefer Go Launcher to Launcher Pro. Glad I decided to keep the experiment going
Also worth noting, between getting rid of LP and installing GL, there was a few minutes where I was stuck back using Blur and I hated it, lol. Recommend anyone who still hasn't tried screwing around with new launchers to just go for it... you can get rid of them in 2 seconds if you're not impressed anyway.
Course now I'll probably need another crisis to convince me to switch to ADW or whatever else is out there
