sure cuts alot vs. Cricut Design studio

So i bought the Provo Craft Gypsy a few weeks ago and I'm slowly learning how to use it. But now comes my next purchase/question? Should i buy Design studio or Sure cuts alot?

I really like the versatility of the Sure cuts alot program. Being able to cut things without the cartridge seems to me like a win win. but then i wonder if provo will eventually have a program similar to scal. I am very close to making my decision and really would like to know if any of you use either program? I have used the trial version of DS but never have tried the SCAL. Let me know what you all think!
