I personally like the Feel of both GB and ICS. To be completely honest GB runs fine for me. However I did make the jump to Ravers Black edition and must say I am falling in love. But, there are some things I do not like and this is not Ravers fault... Its ICS itself. The YouTube widget is very homosexual. There is no wifi calling (due to it not being an original Samsung release). And I'm not able to use launcher Pro, it keeps force closing.
With that being said I have moved on to Nova Prime as my launcher. I do like it, took a while to figure out settings and where things are but its good. I believe once the bugs are fixed (like rotation) this will put GB to rest.
