The biggest things with trikes, is that they don't lean when you go around a corner, which is pretty critical to keeping a two-wheel bike from flipping over when you go around a curve.
Three-wheelers, particularly delta trikes, are more like a sailing catamaran, where they want to lean the 'wrong way' going around corners. Tadpole trikes get around this by having two wheels in the front, for stability, 'Granny' basket trikes are typically so heavy, and low geared, that they're really only capable of low speeds, so it's not as much of an issue there, either.
For an example of what I mean, here are some British racing trikes (apparently, that's a thing) You can see what it takes to go around a corner with all the wheels on the ground:
