Well, I just wrapped up our catastrophic experience with Nikon gear in my earlier post, but of course it depends on what you do with it. We shoot wildlife, and that's definitely sometimes harder for the gear than even most open air sports photography events (except shooting extremes such as the Paris-Dakar rally in the Sahara). We are no Eastwoods, we simply do what birders do, if they are a bit serious. But the number of failures we experienced with Nikon over two decades of digital photography can't be just bad luck, in particular because my wife is much more cautious with her gear than me.
Here's the lens I used most frequently in the past 15 years, an EF 500mm f/4.5 L USM made in 1995 (bought it used in 2011 for a good price). It crashed several times on the ground, against rocks, survived sand & salt water storms on shores (shooting seabirds), and it still works, more than 30 years old now (btw it performs quite well on e.g. my R7, even with a 2x TC III on it focuses surprisingly reliable and not too slowly). Only its mount is now so worn off that it has too much play, so I upgraded to an EF 600mm f/4.0 III past year. This I call quality
