You should get out more.
But to really get to the meat of the question, it would depend on what type of water you are on. On your bigger rivers, I would tend to agree that a jet would probably have an advantage. You will have the added comfort of advanced electronic and a trolling motor too.
But on smaller waters, such as I fish, I would have to lean towards the canoe/kayak. You will be able to float over many areas a jet would most likely have to be pulled over. And when you get to a strainer, well I certainly know which one I would rather have to mess with.
But for overall access to stream and rivers of Missouri, I will stick with my canoe. And I just have one because that is all I can fish out of at any one time. And if I decide to go by myself, I just put 80 pound lead ingot that I have from Doe Run in the front. I have been thinking about getting one of those sawmill slabs that you stand on and paddle around. That sounds like a lot of fun.
