I’m starting a large vanity and will be cutting a number of sheets of pre-finished plywood down for the interior.
I’m okay with buying a track saw but I’m happy with my circular saw and I can easily and cheaply make a track for my circular saw to cut the panels square and fine tune (if needed) on my table saw.
I’m just trying to understand what advantage buying a track saw would be. The saws that go with them appear to be lower powered saws (I’m sure they’re adequate for the purpose).

I’m interested in those with experience either way what if any advantage the track saw has.
