The best cookset is the one you're willing bring and use. Whatever gets you out there enjoying your time.

I would hate it if someone told me what the ultimate cookset is. Over the years, I have collected a pretty wide array of pots and cups of various sizes and shapes (usually on deep discount) and each of them seems optimized for a specific purpose. Therefore, I tend to decide what I want to bring for any given trip depending on what I'm going to be heating in it, but you can make nearly any set work. IMHO, the differences are pretty minor. I just enjoy tweaking my kit because it's fun for me to think about this stuff and learn what works marginally better for my purposes.
