Larger wheels - easier to turn?
Larger wheels have lower effective rolling resistance.  That is, they roll over obstacles more easily and smoothly because the larger diameter doesn't allow them to fall into gaps as easily.  Which means on actual roads you'll roll more easily with a larger wheel.  Everything else is much smaller differences.

However, I think the angular momentum may work out about the same: at the same speed, a bigger wheel will have a lower rpm than a smaller wheel.  And the ratio of the difference in rotation speed is the same as the ratio of the the angular momentum.  To put it another way: I'm too lazy to work out all the math, but I think the angular momentum cancels out and you get the same linear momentum regardless of wheel size. (and having the same linear momentum is an intuitive result. If you're going 15mph, relative to you the bottom of the wheel is going 15mph back, the top 15mph forward, the front 15mph down, the back 15mph up.  Relative to the road it's 0, 15, 15 and 30. All independent of wheel size)

Constructing a larger wheel will generally require slightly more mass and might therefore slow your acceleration slightly.

Also, all else being equal, a larger wheel is geared higher and may give you a higher top speed.
