I’ve owned A Yamaha sled, atv, pwc and outboard. All were reliable as an anvil. I’m sorry but the same can’t be said for a Rotax triple. Yes there will always be exceptions. A 20 year old $700 sled could be real expensive by the time it’s reliable, doesn’t matter the brand. As the others have said, might be best to look for something more geared for what you want to do. Neither of those sleds are meant to tow ice shacks.
