I don't know why but cherry is just so much better, don't get me wrong, apple is great but I just prefer cherry. Cherry isn't my fave pie though, I much prefer Strawberry rhubarb pie, or flapper pie, which is a family favorite.
I hate sweet pies like cherry or apple, I'd much rather have a mushroom pie. I'll go with cherry though, anything apple makes me either be sick or feel sick. My body has a deep hatred for apples...
I love apple pie and apples in general, but I've never had cherry. I find cherries too bitter in most cases so I'm not sure if I'd enjoy them in a pie.
