: Which do you guys find to be a cleaner, straighter cut, a circular saw or a
: worm drive skil saw???

the "clean" part of the cut is determined by the blade mostly. match your blade to the size of the stock and the type of work you are doing: ripping, cutting plywood, etc.

As for a straight cut, that is easy with almost any saw if you use a guide.

The advantages of the worm drive saw are the longevity of the motor, the torque, and the design of the saw which permits a right handed carpenter to see the line they are cutting along without having to hunch over the saw. Some of these advantages are true for only some users, though.
