None of those brands has a known problems list longer than 2 pages. Aventon has 6 pages. Small market share may be the reason, but read the posts on the brand forum known problems thread for more details.
My first geared hub motor lasted ~4500 miles due to the plastic gear. 2 1/2 years. It was an ebikeling, a real low end product. Cost $221 with wheel, controller, throttle, PAS pickup, brake handles. I wouldn't worry about the motor brand, a geared hub motor is easily changed out with another brand as long as the connector matches up. I would focus most on ride position and frame size fitting you. I ride cable pull disk brakes, the cheap tektro ones, and really like them. Changing front pad @ 5000 miles took about 30 minutes, an allen wrench and plier. Read some horror stories about hydraulic brake maintenance on the maintenance thread. Note cheap air suspensions are short life products. I don't have one, I ride a hard suspension cargo bike.
Trek for their price produces a product that has one of the shortest lists of known problems. Their market share is huge.
I see in your other thread you are in North Idaho. None of these geared hub motor bikes will climb 1000' in an hour. They will overheat & burn the winding. I climb >80 hills in 3.5 hours on my geared hub motor bike, but my total rise is ~200'. Three hills are 15%, and I carry 60 lb supplies up them, but only 100' long. If you are not climbing mountains with the bike you shouldn't need the expense of a mid drive. If you are, plan on another $500 for mid drive plus chain replacement every 2000 to 500 miles. 9 speed up chains require more frequent replacement. I get 5000 miles out of my 8 speed chain with a hub drive.
