One presses straight down, the other drags along. Every other difference between them follows from that.

A rocker is a long curved blade you press straight down while rocking it across the pizza. The cutting force is vertical, the blade barely moves horizontally, and a 14-inch rocker crosses a 14-inch pizza in one press.
A wheel is a rolling disc you push along. The cutting force is a combination of downward pressure and forward motion, and the blade travels the whole length of the cut.
Every difference below comes out of that one distinction.
| Rocker | Wheel | |
|---|---|---|
| Cutting motion | Vertical press | Horizontal drag |
| Topping displacement | Minimal - nothing pushes along the cut | Real - toppings pile at the far edge |
| Passes per cut | One press | One to three, depending on the crust |
| Thick crust | Good, if the blade is long enough | Stalls unless the wheel is 4 inches or more |
| Effect on the surface below | Presses the full blade length into it | Drags a hardened edge across it |
| Storage | 14 inches, needs a sheath | Fits a drawer |
| Cleaning | A single flat blade, easy | The axle traps cheese |
| Safe on a stone | No | No |
One press
What a full-length rocker buys you
A 14-inch blade crosses a 14-inch pizza in a single movement, so nothing gets dragged and nothing needs a second pass. That is the whole argument, and it is a good one.
Rocker. Heavily topped pizza, where drag would rearrange everything. Thick crust, where a wheel stalls. Anyone cutting on a board and with somewhere to store 14 inches of blade.
Wheel. Thin, lightly topped pizza. Small kitchens. Non-round shapes and trimming, where a long straight blade is the wrong tool. And it is the cheaper option by a long way.
Neither, if you cut on the stone. Both press or drag hardened steel into the surface. A wheel leaves gray metal marks on cordierite; a rocker will take seasoning off a steel in a line. Scissors with a spatula base are the answer there, or move the pizza to a board.
Rocker: at least as long as the pizza is wide, or you lose the single-press advantage and are back to overlapping cuts.
Wheel: at least 4 inches in diameter. A smaller wheel has a steeper approach angle, so it pushes the crust ahead of itself rather than cutting into it - which is why cheap small wheels feel blunt even when they are sharp.
Scissors with a spatula base cut with a shearing action and keep the blade off the surface entirely. They are the only one of the three we would use on a stone, and they are slower on a thick base. Full ranking in the cutter roundup.
We have not baked on any of these. Every guide in this category says it tested a dozen stones; we would rather say plainly that we did not. What we did instead is on this page in full: published specs with their sources, thermal arithmetic from material constants with the working shown, and the makers' own manuals read rather than paraphrased.
Checkered Chef
Fourteen inches of blade cuts a 14-inch pizza in one press, which is the only real argument for a rocker. It also means 14 inches of blade pressing straight down onto whatever the pizza is sitting on.

OXO
A big wheel with a thumb guard. The cheapest competent cutter here, and the one most likely to drag a hardened edge across a surface you did not want marked.

Dreamfarm
Scissors with a spatula base, so the blade never touches the surface underneath. On a stone or a seasoned steel, that is the whole argument - a wheel drags across the surface, and this does not.
