I have a few of both styles and can't say I'd buy another but I like what I have, and both have their plus and negative attributes.

Porting doesn't add weight but on mine gets the front sight dirty double quick. FO sights get black on my Ruger .357 Blackhawk and then there's a concern that the heat may melt the FO?

My Springfield V-16 recoils a bit less than my 5" 1911's and it's pretty well accepted that a bit of velocity is lost on Springfield's many ports on the V-16 but the added weight and length is an issue but it's a fun gun to shoot none the less.

A Comp is IMO better at reducing recoil but part of the effect is the extra weight at the muzzle, and on the down side adds length and weight.
