if you want to "beat the car like a rented mule" then the 6mt in the spec be is preferable. It will take launching better. the 5mt can hold 300+ whp but it cant take the shock of launching the car at high tq levels like the 6mt can. trust me.
and if you want road race suspension, i have a set of AST's for sale.
