Well for me the ota updated my base band from 10p to 13p. So thats always a good thing to have your radios completely updated. Other then that, maybe some minor bug issues have been ironed out and thats all. The one click rooter works like a charm for the ota...nice and easy. :icon_ peace:
dont flash the current OTA Kernel based roms over the leaked kernel, i tried the same thing, and ended up with boot loops shortly after lol. I may have just been unlucky, maybe someone else has flashed new roms over the leaked kernel without an issue, but from my experience id say dont try it.
