Both, Sea&Sea and Inon don't work with the Anglerfish slave trigger and a homemade optical cable. For both the China/Ali express cables don't work.
Directly on the camera the most easy selfmade cables work, but the Anglerfish slave trigger only gives a weak led signal, so the original cables are needed.
The screw on method of Inon cables is stronger, you only have now a push in connection on the slave trigger. This means 50% less change of pulling the cable out by accident (and yes, this happens when cave diving. This is a + for Inon.
Depth, 100m vs 75m. As I dive sometimes over 75m and sometimes over 100m, another + for Inon.
Speed, Inon has a faster recycle time. Sadly, you really see the difference sometimes. The Inon flashes, the seasea you have to wait. Another + for Inon.
Amount of flashes out of 1 set batteries: I never had problems with Sea&Sea, but on paper the Inon is again better. I will say +/- for Inon.
Auto-off. Really annoying with Sea&Sea on some dives. So another + for Inon.
Battery compartment and O-rings. I like the design of Sea&Sea more, but don't know if there is a real difference in durability.
Price, The older Sea&Sea was way much cheaper. But not available anymore (it was when I started the topic, 1 week later it was sold out everywhere). The new Solis is much more expensive than the S2000. I have to buy a new original cable too, then the price for the Solis or the S2000 is the same. I asked if they could do something with the price of the Solis, but till now no answer. If there is no answer coming, I think I know what I want to buy.
