Although I have paddled a lot of other kayaks which had more room, were more responsive, or easier to roll, I have never found one that had all of these characteristics rolled into one boat. Because of this, I am still paddling my Tesla after all of the years. And, I see no reason to change.
I actually have the older version, not the NM. The only difference that I know of is that it's 17' instead of 17'10", and Necky's newest boats have recessed deck fittings. Anyway, with a 25" beam, it doesn't lean too well. It's not as playful as the British boats, and with the rudder on deck it weathercocks alot. I don't like the seat, however I haven't done much about it! The neoprene hatch seals can be a pain, although they're very dry. There are alot of deck bungees, but no lines so I added my own.
So why do I keep it? It hauls tons of stuff for camping trips, and with the big hatches I can bring a full-size tripod, etc. It also has alot of initial stability, so I can easily photograph from it without having to worry about the stability of the boat. It's also very well made and the finish quality is excellent. I'll keep this boat for longer trips where I can paddle it loaded (too big for me to paddle empty) or when I want to photograph from it. It's also a forgiving boat for a beginner if a friend wants to try it. So the bottom line for me is that it's a good boat, but not exactly what I'm looking for in most of my paddling.
Two minor gripes: The pedals can slip backward towards the paddler making recovery difficult. Solution was to tighten the bungies. The other gripe is the polyester line for deck lines and rudder. The cord stretches when wet allowing the rudder to come out of its rest. I am working on a fix. If there is a better boat for me I was unable to find it.
