The Mobile Fidelity UltraDeck spins its platter via belt drive; the Technics SL-100C uses direct drive instead. Neither is objectively better — a motor that's mechanically isolated from the platter by an elastic belt, which is the usual route to a quieter noise floor — the default choice across most of hi-fi versus instant start-up, rock-steady speed under load, and enough torque to nudge or backspin the record — the reason DJs and scratch decks are built this way.

Bottom line: the Technics SL-100C has the lower reference price; the table shows which documented features change with the $99 gap.
