I would consider the Cosmic Crisp an eating apple and as I mentioned before, I think the juice flavor is great. For me the texture is more reminiscent of a asian pear apple, than a regular apple. That might be what roguequilter didn't appreciate.
Those home/unknown/heirloom apples can be great, and you want what wants to grow, not what you have to baby along. Same thing with old root stock roses.
Jazz is another apple I like and recommend.
