How much all the new technology and what not adds to the fin is open for debate. How much do you really need anyway? For the recreational diver, we just need a comfortable fin that allows us to move through the water without thinking about our fins. We're not in a race or in a competition.
Personally, I would just worry about comfort the most. Doesn't matter what the fin has, if it's not comfortable, you're not going to have a great dive.
