While I have tries most types of fins out there, For twenty years I used jet fins, and I still find them best for current or anytime I really want power. My wife however, did not like hers, and the more I did photo dives the heavy Jets were not the answer. I use my Atomics now for about 75% of my dives, to get the most out of them you need to use a proper style of kicking which is less knee, and shorter vertical movement. The result is it appears i am barely moving my legs but I move along at a normal pace. I have been really happy with the company, I've had two things happen that I reported, in both cases, a fedex package arrived the next day with a replacement. They only asked that I return the original so that they could determine the failure. Since the replacement (~200 dives ago) I've not had a reason to complain. One nice thing about splits is using one leg to rotate and help keep photo shots set up.
The downside is if you dive currents or want to do towing ( like a big video rig) they require rapid movement of the legs to get the thrust, that does not work for me, and would prefer the stiff jets where a wider kick achieves the speed. Atomics are also long, and just barely fit some of the travel cases.
One odd note, I tried using free diving fins while diving warm water, and found those to be superior in thrust to my jets. However, those are not practical for my photo.
