I use TSF Shell (a very pricey 3D launcher) and it's currently my favorite and can do so much but with half the memory footprint of Go Launcher. it's my daily driver on my Galaxy Precedent and refuses to lag so far (although i did a lot of root hacking to make it that way lol). for my lockscreen i use Widgetlocker with various HD Widgets for some toggles and the date/time and use Go Weather EX Moonlight theme widget to show weather info (doesn't require the launcher and blends in with HD Widgets--on lock screens the HD Widget weather clock won't update automatically).
I'm going to get Nova Prime on my Galaxy Tab 2 though, after i finish this ROM flashing stuff. if anything to restore the iOS badge alerts i miss from my iPad. now if i could get badges without requiring icons on the status bar. so tired of hitting 'clear all' every few hours. from my experiences with Prime on my Kindle Fire running 4.1, the icons must display on the status bar (well, they will anyway if your app has the notifications turned on, required by MissedIt!) which defeats the purpose of badge counters. i simply can't stand having so many dotting my notification area. prefer it the way iOS does it, with a clean status bar and the notications as part of the app icon itself.
i wonder if the status bar apk can be removed without crashing the device. that would work too, and for things like battery level and whatnot, i got widgets for that
