If plywood is solid hardwood ply like Baltic bitch, and through the ply not in between then yes would be similar, if normal plywood with junk soft wood core then totally different. I’ve been tapping solid hardwood ply years, MDF will be similar results but does seem to benefit from ca glue. Corse thread wood screws (with correct pilot) seem to be just as strong, but only 1 time use and if not over torqued. Without the pilot very different results. Well that’s been my experience anyway as a home woodworker for ~30 years I have tried those inserts a few times over the years, but never got as good results as tapping.
