What is the actual difference between buying a Snowblower at a big box store (HD, Menard, etc) and a Lawncare/Snowblower dealership?

I hear everyone recommend going to the dealers instead of the big box stores but I'm not sure i understand the appeal.

In my initial research it seems like pricing would be roughly the same, and I could be wrong, but I'd actually feel like I'm going to have a more reliable, consistent experience with the bigger stores I shop at all the time. If there's anything wrong, returns, etc; I at least know the policies of the larger stores and can easily follow up with their customer service, escalate to management if needed, etc.

In addition, I'm having to go at least a few miles further to go to the Snow/Lawn dealers. Not a huge concern but just another factor.

So can someone clarify why going to a smaller dealer is so much better and if it's the right choice for me?

For reference I'm looking to get either an Ariens or a Toro. Thanks in advance for your input!
