I own both, got on Ok with the cressi foot pockets but the Omer ones are much more comfy. Omer Ice definately have the advantage spearfishing by being see through they reduce your outline significantly. Omer Ice are also a great 'swimming' fin working very efficiently on the surface, again good for spearing. However depending on your freediving depths I have trouble with the Ice fins at 15-18m+ they lack a bit of rigidity and snap for coming up off the bottom, it could be my technique although I had similar issues with my cressis they definately felt easier at 18m than the Ice.
Basically both good fins mostly should depend on your personal prference and comfort. If you were mostly going to spear i'd say the Ice fins, lots of freediving then I might still pick them despite the drawbacks i've experianced. As stated before the omer foot pockets are used by other companies often and blades can be swapped.. e.g C4 carbon blades (some of) can be fitted to the omer foot pockets. Giving you a chance to upgrade a bit cheaper in the future.
