I think that foot pocket fit with your dive booties is one of the top priorities....I have seen way to many folks with sores on their feet from improper fitting fins/booties.
I have both yellow ScubaPro Twin Jets (split fin) and Jets, a dry suit pair fitted with SS springs, a warm water pair with the standard straps.
I started with the Twin Jets, and my wife bought a set of plain paddle fins (can't even remember which ones), she kept getting leg cramps at the end of longer dives so one day she took my Tiwn Jets for a dive, from that day on she has used the Twin Jets exclusively. When our children became certified she immediately got them there own pair of yellow Twin Jets "no child of ours shall ever endure the pain of leg cramps" hers were pretty bad.
I found a pair of very, very used Jets (old rentals no less) at a local dive store clean out sale for $5 and used them for a few years when we all dove together, then one day she found 2 pairs of Jets (still in the boxes) at a yard sale and bought them for $10 a pair, deal of the year, those are the ones I use now.
I like the "control" and size of the Jets (easy to pack, as they are relatively short) but leg cramps do happen, I like the Twin Jets as they feel like there is nothing on your feet, they are just so easy to dive with.
Jets are heavy - which can be an advantage in a dry suit as you may not need ankle weights if you currently use them.
I have used both fins in a dry suit, with doubles, with a camera and other than "fine control" I prefer the Twins. From my perspective (unscientific) Jets accelerate faster but Twins are easier to hold at top speed for longer, as in trying to catch up to a dive group after lingering far to long in one spot to try and take a picture or if long surface swims.
My son and I dove the Yucatan Cenotes last summer him with Twin Jets me with Jets, we both moved easily through the water without kicking up silt.
My recommendation is to try a bunch on fins before you buy a pair, your fining style may dictate a preference for one versus the other.
Just my thoughts...M
