Short answer: Addmotor Grandtan M-340 wins this one, 9.2/10 against 7.6/10, mainly on price and brakes and stability. Addmotor Greattan L answers with payload.
Same family, same 750 W rear motor, same 4-inch tires and torque sensor. The Greattan L is the Grandtan idea stretched to carry a passenger: a rear seat for about 150 lb, footrests, room for a second battery, and 82.7 inches of length against 77.6. It costs $1,500 more and, at 36.6 inches wide, will not pass a standard interior door. The Grandtan's page lists triple disc brakes, a parking brake and a differential; the Greattan L page we read lists none of the three, which is why it scores so much lower. If you ride alone, there is no reason to buy the L. If you ride with a grandchild, ask Addmotor about the brakes, then enjoy it.

Addmotor Grandtan M-340: disc brakes on all three wheels, with a parking brake, and a rear differential. Addmotor Greattan L: the product page does not describe the brakes; no parking brake is mentioned; no differential is mentioned. On a trike these three parts do most of the safety work: hydraulic brakes need less hand force, a parking brake holds the trike while you get on, and a differential lets the rear wheels turn at different speeds in a corner.
Addmotor Grandtan M-340: 750 W, 960 Wh of battery, up to 85 miles on assist level 1 (Addmotor), 20 mph top speed. Addmotor Greattan L: 750 W (1,400 W peak), 960 Wh of battery, 65 miles on one battery, 130 miles on two (Addmotor), 20 mph top speed.
