I've owned and fished out of all: pontoon, tube, but for what you're looking to do, especially keep dry and not have to put on waders, Stand and cast, don't forget relieving yourself (I carry a port-a-john), the pram is the way to go IMO. I recently bought an 8' ultra light aluminum welded pram, which is so light, I can lift it easily. It fits in the back of a Toyota truck and its pretty much maintanence free. Can leave it outside, not worry about pumping it up, corrosion, or durability. I used it in the salt for Pinks and it did well. Plus you can mount a double anchor set up and it doubles as a Chironomid fishing machine. Go see what the guys in BC use, and you'll quickly be a convert into the pram world.
