My favorite pies are cherry, pecan, and pumpkin. I enjoy eating pie with ice cream and sometimes whipped cream. One time I bought a cherry pie and my friends and I went to see Wall-E and we ate the pie while watching the movie. Best decision ever.
I also enjoy apple pie, peach cobbler (not sure I've ever had the pie version, but they're similar), key lime pie, and others, but each has a problem that keeps it below my top three. For instance, I don't like apple pie as much because the apple chunks don't really MESH with the pie, they're too large and distinctive. The flavors are together but they don't blend perfectly with the crust and everything else.
I love Natchitoches meat pies. Shepherd's pie is also pretty good.
