I rented one for a couple days in W Yellowstone. 450 Husky with a Mototrax kit.
Before renting I never would have said E start was a must, but I've changed my opinion. Could be my personality, I'm sure it's is, but I ended up in too many pickles with steep side hills or whatever where just getting back up and moving was tough. The thought of kicking...nope, not me. Must have a magic button! Must! Again, it's just me and I do tend to find a challenge. Better riders may not.
Power loss up high was significant. Get as much as you can.
Let us know what you decide to get. I'm curious to hear as well.
