I get about seven yrs out of a suit (so probably about 50 OWS). During that time I'll make occasional aqua seal repairs and probably 1-2 seam fixes w/Ironmend. That's for high end, full sleeve suits (B70 helix, etc.) that use thinner materials. I've gotten longer life from lower end suits (thicker rubber) and sleeveless ones (no thin arms/shoulders to cut/rip). Also, at the start of every season I do the Emilio trick of soaking the wetsuit to restore some elasticity.
