I agree with Willi. Get in the water with someone nearby ready to help, and try it out.
Comfort is a pretty relative term when you're discussing comfort of a dry wetsuit vs. comfort of cold clothing. And once you're in the water your strength fades quickly. I can guarantee you the choice will be made for you once you've spent some time in cold water with and without a wetsuit or drysuit, and some time warming up afterwards.
I think if you're planning on learning anything in a boat more capable than you are right now, you ought to plan on getting wet. Which means preparing as if you're going to get wet. In conditions that kayak would be easy to capsize. And if nothing else, wear one for the people on shore who care about you.
