I sell both. I've shot Ike P&S as well as the Nauticam d300s as well as other plastic housings.
I think the major differences are bulkiness, controls, fiber optic vs. hard-wired sync. The Nauticam ports are modular, locking and use a bayonet mount that is much more durable. The Ike modular ports are much better than their old plastic ports, which aren't the best. As far a leak control the Nauticam has an audible and visual alarm as standard.
One lever to switch between live view and video, no shared controls, and much, much better ergonomics and size are big differences.
I've sold the Nauticam D90 to a customer using a Ike bulkhead, TTL converter and DS-161 strobes and they are ecstatic with the results.
I substitute my metal arms with orings for the Ikelite arms in packages (same price), their plastic arm sets are, well, kinda lightweight and don't hold.
I think one thing you have to ask yourself, is this the manufacturer you'll want to grow with in the future? You're going to want to hold on to strobes and ports as you upgrade.
There are cost advantages to the Ike, no doubt, and you tend to get used to what you have as you shoot.
