I've purchased and built several complete kits and I believe that I like the monthly subscriptions better. On the full kits, I find that I finish the kits too quickly. I become obsessed with completing them and do not savor the experience. For me, I think that will just do the subscriptions from here forward. Also, I agree with ThomasJW, if you have enough subs, there is always something to build. I really love this hobby and hearing from my fellow modelers.
