Would these radiators make a big difference?

If i were to spent the extra 200 bucks to buy a 38 mm Fluidyne radiator for my 87 Supra (http://www.suprastore.com/fluidrad19su.html) would I be missing out on a lot if I bought the Mishimoto radiator (http://www.mishimoto.com/toyota-supra-performance-aluminum-radiator-86-92.html)?
