Again I must apologize for not turning up the sarcasm gain so that it was clear.
For river diving, or if I need to dive a wicked shore break whenever it is important to accelerate fast, move fast over a short distance and not care about the bottom ... can't beat duckfeet (as long as your legs are ready for it<G>)
My old FaraFins (basically a Jetfin with spring straps) are just the ticket for a situation that calls for fine maneuvering over a silty bottom.
For a long swim through a spread out set of rolling breakers I like QuatroPros with Farafin spring straps.
Cressi Rondine Garas for freediving.
I'm finding that I like the Idea3s for long slow swims and when I have to push something,
I haven't quite figured out what to do with the split fins and the forcefins yet, but I've only used on an twenty or thirty dives each, any advise for these.
These are all personal feelings and likely have more to do with the different ways in which I kick each fin, I have friends with different preferences for the same models.
