Either could work for you but I think you'll be happier with the 3 speed for mostly street driving. That said, you're aiming for over 1,000 hp and while a 727 will hold that the closer you get to 1,500 hp the better choice the glide becomes. If you ever plan on stepping up the power (which is easily done with boost) then you might invest in a well built glide for the long run.
