The bigger the wheel, the more of a "vehicle" the unicycle becomes. It
can take you from one place to another, whether along the road, around
the park or through the woods.
The smaller the wheel, the lighter and stronger the uni is, and the
easier it becomes to do clever technical stuf, whether that is
freestyle or hopping jumping up an down on the municipal flower beds.
The difference in wheel size between 20 and 24 is not "only 4 inches",
it is 20%. That is, a 24 is a fifth bigger. That's a fifth heavier, a
fifth more leverage back through the cranks, a fifth more wheel to turn
in tight corners.
The difference between a 20 and a 24 is bigger than the difference
between a 24 and a 26, or a 26 and a 28 - or even a 24 and a 28.
If you want to "go places", consider a 26, 28 or 29.
If you want to do clever stuff in one place, get a 19 or 20.
