It is regional until you try both side x side and it also depends on if you are right handed or left handed and you cut a lot of roofs and stairs. I've used worm drives from Skil, Bosch, Makita, and one more that I don't recall the brand of. I have a couple of sidewinders and I've used them from smallish to monster beam saws from Makita along with a few trailer mounted radial arm saws swinging 24" blades.
You get to use and try a bunch of different saws when you spend several years as the saw man building custom homes. I cut all the studs, fire blocks, vent blocks headers, king studs, trimmers, and beams for the homes we built.
After we finished the framing, we set up a mill in the garage and I ran the table saw for the cabinets we built. In and amongst that, I built the door jambs and prehung all the interior doors for the finish carpenters.
I currently own 2 sidewinders, 1 compound radial arm chop saw, 1 regular chop saw, 4 jigsaws, 4 worm-drives, and a couple more oddball saws.
If you told me I had to get rid of everything but 1 saw, I would keep the worm drive.
