I like all three for there own reasons. As for BKSOR. I put a bunch of games on a pro and thought I could do without the upper. Then we got a prem at league and really like the upper now. So I would go with a Prem or LE.
Oh ans since you mentioned the button. If I get one I will put it on the side. Sure you can play the way it is but why not make it more enjoyable to whom ever owns the game.
