I too have a big fretsaw(the one with the oscillating arm, plus a couple of the smaller ones that use a magnet to move the arms, all cut well and clean, without overly splitting out the sheet (as you get with a jigsaw), it is slower than the jigsaw, but more precise and greater control, if I want to cut the thicker material, I will use the bandsaw, the fretsaw however does tighter radiuses. so each saw has its place. I also have a hand fretsaw for really delicate work, and a coping saw for slightly bigger curves.
