Stark or Arctic Leopard (XE, "Cheetah") — which to choose?

Arctic Leopard E-XE 880 ("Cheetah") — per sellers' data: about 108 kg, peak about 37 kW (~50 hp), battery about 6–6.75 kWh, noticeably cheaper than a Stark.

Stark Varg EX / MX 1.2 — 120 / 118 kg, 60–80 hp, 7.2 kWh battery, liquid cooling of motor, battery and inverter.

Opinions in the chat

• the Arctic is lighter and cheaper; about 1.5 times less powerful, comparable range, and at an easy pace it may go further
• the Arctic can overheat on hard climbs — the Stark's cooling is better
• there are complaints about the Arctic's build quality (caliper centered with a washer, a loose bushing in the wheel, plastics); an owner who rode one for 10 months complained about suspension and power, switched to a Stark and is happy — the only thing he liked about the Arctic was the weight
• an Arctic seller in the chat notes the Leopard only needs charging and gearbox oil, with no "fatal" problems

In short: the Arctic is lighter and cheaper; the Stark is more powerful, with better cooling and suspension, but heavier and pricier.
