Short answer: InMotion P6 wins this one, 8.8/10 against 8.1/10, mainly on published protections and motor power. Leaperkim Sherman-L answers with price and weight.
What really separates them?
The two biggest batteries on the site: 4,200 Wh and 4,000 Wh. The P6 costs $900 more and spends it on power: 6,000 W against 3,200 W, a 235 V system against 151 V, plus IPX6 on the page, GPS and free shipping. The Sherman-L is 9.5 lb lighter, has the higher load limit (320 lb against 309 lb) and accepts 20 A charging. For touring at moderate speeds, the Sherman-L does the same job for less. The P6 is for the rider who wants the largest power reserve made, and rides in conditions where a published water rating matters.

Which one has more power and battery?
InMotion P6: 6,000 W (20,000 W peak) motor, 4,200 Wh on a 235 V system. Leaperkim Sherman-L: 3,200 W (8,000 W peak) motor, 4,000 Wh on a 151 V system.
The P6 has the stronger motor, by 2,800 W nominal. The P6 has the bigger battery, by 200 Wh, a gap too small to feel. As for speed, the published figures are 93 mph, per InMotion; eWheels words it as "over 90 mph in ideal conditions" for the P6 and about 57 mph cruising speed, per eWheels for the Sherman-L. Those are the sellers' figures, not speeds to plan a ride around, and they are not part of our score: motor power is. For range, compare watt-hours; our electric unicycle range guide shows how to turn them into miles.
Which one rides more comfortably?
InMotion P6: dual hydraulic coil shocks, 90 mm of travel, on a 20 in (80/90-14 tubeless) tire. Leaperkim Sherman-L: fastace suspension, 90 mm of travel, three spring weights, on a 20 in tubeless (80/90-14), street or knobby tire.
Both publish the same suspension travel, so tire size and tuning decide. Rider load: 309 lb for the P6, 320 lb for the Sherman-L, gear included.
Which one is easier to live with?
P6: 112 lb, trolley handle built in, kickstand; charging: 4 hours with the 5 A charger; 80% in 1 hour with a 14 A charger, per InMotion. Sherman-L: 102.5 lb, trolley handle built in, kickstand; charging: 3 hours to 80% with the stock charger; accepts 20 A.
The Sherman-L is 9.5 lb lighter, which matters every time stairs or a car trunk are involved. Published protections: InMotion P6, IPX6 and a smart BMS; Leaperkim Sherman-L, a smart BMS. A water rating we can't read on the seller's page is a rating we can't count. Whichever you pick, a helmet and wrist guards go in the same basket: see our electric unicycle safety gear guide.
