NEED ADVICE! 2010 outlander 650 xtp vs 2015 outlander L 500

I am looking to get a new atv for this winter to plow driveways. I am buying used off of craigslist. Currently I am torn between two deals, both are in excellent condition. I dont know if i need the extra power of the 650 or how important power steering is. Keep in mind I will have to shell out ~$500 for a plow and mounting system for the 2015 outlander L. What do you guys think is the best deal? I can afford the spend $6250 but that amount is a huge purchase for me. Tell me what you’d go with if you were in my shoes. i will not do much riding other than just plowing in the winter at least for a few more years when I will have more time
