I think it's easy to solve. When I got one, I scrambled and solved it in the same day. Though I didn't completely know how I did it then, about two weeks later I had figured it out. Also, there are methods for solving the Pyraminx that don't use any algorithms. I think this shows that it is easier to solve than a 3x3x3. (Most methods for the 3x3x3 use algorithms.) It is different than NxNxN puzzles though.
