I had the Vortex Raptors out for a little while today and am really impressed with this this little binocular. Very nice balance for me and light weight and the optics are really impressively close to anything I own. But the deal breaker is how difficult the focuser is, especially in cold weather. I hear this a lot from others who own various brands of these binoculars. I'm wondering if it's true for all of them? I know that reverse porros don't have this problem and don't understand why? Can someone explain and has someone compared the brands and found one that is not such a pain to focus?

Get a Nikon. They have the best focuser. Chinese haven't learned how to make a focuser yet.
Reverse porros usually focus internally by moving the objective lenses rather than moving the long tubes (that are exposed to the elements) which hold the oculars in the regular porros. Although, to tell the truth, I really don't know whether this has anything to do with why the reverse porros focus easier.
