Each will have their own reasons for the tools they buy. I bought the Ridgid 3650 and have enjoyed it for the past 15 months. I added a router taable extension on the right and then added a folding outfeed table. This adds an incredible amount of support and work surface.
As I am a weekend hobbiest, my needs may not push this saw, but I have used it to make a bed, two dressers two bedside tables and a kitchen table among other things. The power is sufficient, the fence works great for me, and the lift system makes it VERY easy to roll around my garage.
Good Luck on your search.
