More or less. A panel saw combined with the track it is intended for will have often have a "zero clearance" strip along the track to prevent a lot of the wood being torn up when cutting. So, nicer cuts.

For me, having the sled "built-in" on a true panel saw makes for a less awkward experience using the tool.

It would be one thing if I went back and forth between using the circular saw and the panel saw but I truly haven't touched my circular saw in maybe ten years now.
