Yes, it is fun to plan. I'm thinking about going out of either Port Canaveral or Miami for my next cruise, and again, getting to the port is mainly what I need to consider, as it will be about the same including transportation to the port including cruise price and transportation price.
Miami is easier to get to from Miami airport, but the cruise is about $30 more than Port Canaveral. On the other hand, the cruise line's transfers are reasonably priced from Orlando Airport to Port Canaveral considering it's just me going (which I'm perfectly fine with).
