What's the difference between a portable folding workbench and a heavy-duty garage bench?

Folding benches (Worx, Keter, Pony) weigh 13–30 lbs, set up in seconds, and store flat, but trade rigidity for portability. Heavy-duty benches like the CAMMOO line use a steel frame with a rubberwood top, claim 2,000 lb capacities, and offer storage shelves, pegboards and power strips, but they're stationary and require assembly.
