+1 to what Mr. X said. I also use the Sprint drivers and kernel in one of my ROMs, and there is no bad effect but maybe the effect of a little more smoothness all around, the drivers and kernel are completely fine. As far as the manila compiled for them, it is pretty much the exact same except a few tweaks to the people and messaging tabs, and the addition of sprint nav and tv tabs as the two versions of 2012 (sprint and what most chefs use) were compiled less than 24 hours apart. Sprint just threw the update together quickly without testing for long and applying appropriate fixes hence some of the issues people have and some of the cabs you have to install to fix things.
