Folks, I'm preparing to prime the interior of several areas around the house prior to painting them again. I used to use Kilz Latex primer with really good results but now I've noticed that there are all sorts of other variations both within Kilz's line and of course other lines including Sherwin Williams which is what I primed and painted the exterior with. Can y'all share some wisdom here please? Thanks. 

Anyways, I've always gotten good results with the regular Kilz latex but now they have Kilz 2 and Kilz Premium which I guess isn't really Latex but is Acrylic. Anyone else with experience or expertise here? I'd love to learn what works and what won't. Thanks.
