I think you'll find that the vast majority of people who have been on both sides of the fence (like myself) can give better opinions than those who've only tried one type.
Personally, I liked my Apollo split fins until I tried ScubaPro JetFins once I wanted to move to a hogarthian setup. After I tried the Jets in the pool the first time I instantly hated my splits. First off, paddle fins, like JetFins or the Hollis F2's I have for travel offer much, much, much greater control, maneuverability and speed in the water, plus they are on average about half the price of splits.
