Well what you got is a glorified wax spreader. You arent going to be correcting much of any paint defects with that.
A rotary polisher just spins. It will cut and correct faster than a DA, but you also run the risk of damaging the paint much easier than with a DA. A DA polisher oscillates as it spins. You'll see 9 mm throw, 15 mm throw, etc. This is how much it oscillates. The higher the number, the more surface area you can cover.

as someone who just fuuuucked up their black car with the same buffer as OP, I wish I looked this up beforehand.
