I have a Wave and a SuperTool, both of which I've found to be solid and reliable. I carry the Wave daily and think it's a great piece for the weight, cost and versatility. Never used it in a war zone, but it should serve you well if you don't try to replace your entire toolbox with it. I have no experience with the SwissTools. I'd recommend getting your hands on each of the pieces you're considering and see how they feel, weigh, etc.
