To answer your question properly, some reloader would have had to set up a controlled test of case longevity, with a set of cases divided between side-crimp and non-side-crimp techniques, loaded the same except for the crimp. I cannot recall any posts on this forum reporting results of such a test.
Some anecdotal information bearing on your question: I have some cases that have been reloaded 17 times, with at least half of these reloads requiring use of a side crimp. Almost all loads in these cases have been run above the SAAMI pressure max in my bolt rifles. I certainly haven't babied them. I performed a FL resize with each loading. I anticipate getting some more reloads from them.
How many reloads are you getting from your cases?
