The numbers on Makitas bevel gauge are to the right of the marks they correspond to, which makes it easy to set the wrong angle.
There is less chance of error when the numbers are directly below the marks, as they are on other saws, including the DeWalt.
If a saw takes a fall, the slide arm may bend and make it hard to change the depth-of-cut. Milwaukee stiffened the 6477-20's slide arm by rolling its edge.
Some blade guards, like the ones on the Milwaukee (shown) and Makita, have a tendency to snag on compound angles and narrow trimming cuts.
The guards on the Ridgid (shown) and DeWalt will retract by themselves no matter what kind of cut you make.
The base plate on the Ridgid is more likely to bend in falls because it is essentially a flat piece of metal.
The Bosch is sold in two versions: One has a standard cord, and the other — the Direct Connect model — connects directly to an extension cord. Replacing the cord is easy, and you can use any length you like.
