Plenty of solder fittings leak in years to come, that is where they pull apart after years of floor walking. Cap[liliaqry joints made by a builder not a plumber are time bombs, I frequently go to joints that were only pushed in a few mill.
No reason to suspect any better or worse performance from pushfit joints, as long as they are dry when you've first fitted them, the pipe is unblemished, the joint is brand new, copper pipe is cut with a rounded external edge not flat, plastic cut with correct tool, pushed fully together, can take some forearm strength which we have developed on the job you might lack.
