The Prijon Kodiak would tip, roll, and dump you out doing surf landings, and the Tempest wouldn't at all. That's probably the toughest part to put a finger on. I can't judge skill level, the number of experiences we are talking about and the conditions on those days, the particular behaviors or properties of the Kodiak that made it difficult for you to handle in the given conditions.
Anyway, you stated a concern about manageable surf landings, and a sea kayak with a lot of room for camping gear vs. other sea kayaks.
The Current Designs Nomad, which was originally named the Extreme. I'm pretty sure all of the CD ruddered kayaks come with gas pedal style rudder controls now, and if you can get an earlier one, like the Extreme, used, it's easy to upgrade those pedals. It's got a lot of room for camping gear, no skeg box to work around, and my hatches still stay dry after many years of use. That's the minor stuff. The fun part is that it is very well balanced in the wind, very well mannered in rough water, a nice stability profile, and a fast, efficient hull design. I like to describe it as a big Cadillac or Lincoln. Everything feels smooth. It corners very well given its size. It doesn't have that fast "feel", but it's like those big luxury cars, where you look down and realize you're flying and didn't realize you were going so fast because it never really "feels" like it compared to being in other vehicles. I've done many successful rough water landings in mine, both loaded and unloaded, where others have gotten toppled. A lot of that can be how the paddler handled the particular kayak at the particular surf landing, but I will say that it feels easy to manage surf landings in it to me.
I've got a video here from yesterday doing some surf landings in it unloaded. I think it's important to practice this stuff in your expedition kayak, because safe landings out camping in more remote areas become more crucial than landings at a play spot near your car and/or other help. But you can see me surfing in a number of times.
