I noticed in the Mad Max video above they were always going DOWN that steep gravel hill, never going UP. I doubt very much they could get up. I have a Scorp FS and a Lepus delta with Diff. NO comparison. On a steep gravel hill my Scorp ended up in a ditch-first and last time I ever walked a trike up a hill. The Lepus ate the hill for lunch and scrambled up like a mountain goat. The problem with tadpoles offroad-the first steep even semi-steep muddy, gravelly, icey etc. hill they meet, you are mostly likely going to walk. The Lepus and the Kett with Diff-unstoppable.

How rough is rough? It's easy to overstate how off road capable a bike you need for riding places like crushed limestone recreational trails. My rule of thumb is that any trail that gets moderate recreational use can be ridden on almost anything.
The negative of any trike on less than smooth asphalt is 3 wheel tracks. If you find yourself encountering frequent potholes, bumps or wheel ruts, you'll have to make quick decisions how best to get around or over them. On a trail that gets moderate use, I wouldn't be overly concerned about that either.
I'd choose my bike based upon how comfortable you feel riding it just in general. If you feel comfortable and secure on smooth asphalt, a little chip and seal, crushed limestone or even a little gravel won't bother you very much.
I ride my CLWB Tailwind on singletrack. I haven't seen much gravel yet, but I had difficulty in snow. A second set of tires may solve that problem, but I didn't want to buy and change tires for temporary weather.
