Not really. On/off is a binary setting whereas pulse is a synergic function. They seem similar, but at a technical level they’re quite different.
Pulse allows peak time, background amperage, cycle rate, etc. Stitch functions are “I’m on for xx seconds and then I’m off for x.xx seconds”. If that’s what you have, then you can still get quite a bit done instead of relying on pulse. Newer pulse/pulse on pulse models are technical evolutions but remember; millions of miles of standard MIG has been run for decades without pulse. Just like TIG aluminum at 60Hz.
Modern inverters add capabilities but they are not required to get the job done. They just make some things easier or faster.

two completely different uses as well as tech
stitch is for doing stitch welding, ie doing small beads every so many inches apart. normally you just do it manually but a timer makes it a bit easier and more consistent.
pulse is done typically in spray mode, the pulse is very fast causing a ripple effect, but its still one bead. unlike stitch which is multiple beads. pulse also allows spray mode to be done in all positions.
i usually see stitch mode on small machines used for sheet metal.
pulse mig is mainly aluminum, but it used on other materials especially on bigger machines.
tweak it until it breaks
