I can't answer jet or prop until I have an idea of what style/size of boat you want and how you plan to run it.
Jets have come a long ways from the old pressure pumps, but if you want an outboard motor then prop will be your choice.
If you want an inboard motor things get a little fuzzy between the two options.
If it were me and I was looking for a boat 20-24 foot range in aluminum I'd get an outboard with offshore bracket w steerable kicker and a remote helm station, but you'll need deep pockets.
If my pockets were pretty shallow and I were looking at the used market I'd focus on a glass boat with outboard prop and kicker. You get a lot of fishing room and easier maintenance, and glass rides better than aluminum in most cases.
