Search the Forums here, there are a few threads on the Stak vs the Cuts.
I guess it all depends on what you are going for both Vitamen wise (STaks have a shitload of pills, but are pretty sound). they are a good prohormone and Thermogenic. But nothing too different than a Good Multi coupled with a Decent ECA variant, and a Decent Prohormone stack. They might be better for you pricewise as you get everything in one package.
Just be sure to watch for Toxcity levels of certain minerals if you are taking multis with Stacks
