Brent - I think it depends on how you plan to use the boat. If you want a gear hauler that will last and last, the Seascape I think the Seascape is worth considering. I don't have recent experience with NW Kayaks, but their build quality used to be top notch. For all I know it still is. When my 17 year old was 4 we bought one of the very early Seascape 3s and recently sold it to a friend, still solid as a rock.
But if you want to paddle fast, especially without a big gear load, I agree there might be better tandems. I always really liked the Seda Tangos. I don't have any experience with the Necky Nootka, but folks I know like it.
All these boats have, or at least used to have, poor rudder systems that utilize sliding foot braces for rudder control. The first thing I did with our Seascape was retrofit it with a SmartTrack rudder system.
Best,
