All I skate in are Mids, and I've tried a ton. IMO, there is no such thing as a 'best' because everyone has different things they look for in a shoe. It's all subjective and personal preference. If you are looking for ankle support, you don't need anything super bulky to give you support. Even a 'thin' mid will give you the lateral support you need just by it's design. All that extra padding doesn't really do much other than get in your way. There's very little functionality in a super padded shoe.
The list is way too long to post but some of my recent favorites (past year or so) have been: iPath West Wing, Nike Hybred, Nike Toki, Habitat Guru Hi, Adidas Seeley Mid. The Emerica Romero Troubadour is a great shoe too, but I bought the wrong size. The new Lakai Howard Desert Boot is a KILLER shoe, but it's not really a mid. It hits just at or slightly below your ankle bone.
I have a hard time skating in cupsole mids, it's like I can never feel my board. Some people swear by cupsole, but they just don't work for me. That Hybred shoe is a cupsole, and that's really the only one I can mess with.
