Grit grips long slide or sct 17?

I need to decide fast and can only get one. Thinking of two frames, the sct and gritgrips. I have a 17 slide and am thinking of either a full size sct build or going with the grip grips with a different barrel to make it a 17 length slide but 19 grip.

Would most likely just be a range toy, but if I get the gritgrips I could buy 19 slide later and carry, what are your recommendations, is a 19 with a long slide worth it? do you guys like it? I know people favorite frame is usually the gritgrips over the sct.
