Ridgid’s fence is outstanding for its design. Its large front plate helps stabilize it and the whole thing just feels solid. There’s very little play compared to some of the others and we were consistently able to lock it down perfectly square. We like the pinion style bevel adjustment. It’s not quite a good as a separate adjustment wheel, but a great improvement over simple sliding. We also like the independent locks for both height and bevel. It’s not often that a height lock would be required, but there’s an element of confidence that comes from knowing it won’t be going anywhere.
The SawStop Contractor Saw CNS175-TGP36 stands out chiefly on account of its unique safety brake, which stops the spinning blade dead when it senses the presence of skin. However, it's also an excellent saw in other respects: powerful, well built, and easy to assemble, with great dust collection and loads of features. Cost is a major concern, but so is the cost of the injuries SawStop is designed to eliminate.
When your skin contacts the blade even slightly, the charge transfers, and a switch flips on the motor, activating an instant brake. The aluminum brake swings into contact with the blade, stopping it instantly. The brake also propels the blade down through the arbor, so it retracts completely below your worktop. That means that other than the initial contact, you won’t touch the sharp edge at all.

The Bosch weighs in at 52 lbs. While you could carry it one-handed, and it feels well-balanced, it would throw your personal balance way off and tire your arm. The DeWalt is a little lighter at 45 lbs., but it feels even lighter than that, and its weight distribution makes it feel less fatiguing to carry back and forth. (You can also carry the Dewalt saw one-handed by its handle or roll cage, but you probably won't want to.)
We evaluated the flatness of the table by measuring the flatness by placing the edge of a precision ground flat bar across the table and placed feeler gauges in any gaps to measure any difference between the ground bar and the table. TBB took measurements in four directions. As the operator faces the saw, we measured the flatness at the arbor from front-to-rear; we measured the left-to right flatness at the arbor; we measured the flatness from the upper left-to-lower right table corners; and, finally, we measured the upper right-to-lower left flatness between the corners.
