I'm coming from Inquisition. I just installed this ROM a few hours ago and so far there have been some minor issues with things FCing, but I suspect that it was just from me restoring settings from TiB. Clearing the data seems to have fixed most of the problems.
One little issue I've noticed is that uninstalling apps from TiB doesn't actually uninstall them. They remain and I have to uninstall from the app manager or play market. I even uninstalled from the app manager at one point and the app remained until I removed it from the play market. (Weird?)
I'm waiting for my SMS's to finish restoring and then I'll really start testing things out. I did notice that the phone is faster than it was on Inquisition (likely from the lack of Sense stuff), but it certainly doesn't seem as responsive as far as the touch screen. I think I'll need to play with it more to see. Once I have the ROM exactly how I want it, I can switch back and forth between OpenSensation and Inquisition. I'm not brave enough to try this with Boot Manager yet.
I should note that setup wizard FC'd on me on the first boot. Aside from that and the stuff that needed the data cleared things have been pretty smooth. I haven't taken or made a phone call yet, but I'm going to cross my fingers that it all works.
Edit:
Just had a reboot while trying to take a screen shot.
