Im not loyal to any brand camo. Too many different ones to choose from anyway so I never really put much thought to it. Except whats cheaper or onsale. Mostly use Army surplus woodland camo pants and whatever jacket. works for me.
Hide your silhouette, and you're in business. Once the temps start to drop, any open pattern plaid is my camo of choice.
Don't feel quite as stealthy though.
If forced to choose between Realtree, and Mossy Oak, I'd go with Realtree.
