Cartridge reliability

Not having purchased a cartridge in at least 15 years, and probably more, I’m curious what has been your recent experience with cartridge reliability. Any cartridge failures? Significant channel imbalance? Loss of a channel? Suspension collapse? Etc. My focus is on moving coil cartridges.

I’m trying to get an idea of which manufacturers are tops in terms of reliability/QC and which have a thing or two to yet learn. I’m asking as my cartridge, though still sounding quite nice, surely can’t last forever. 
For instance, I’ve read about some albeit quite rare problems with Lyra, but I can’t recall ever hearing about any Dynavector issues. I have heard of some issues with Goldring 

your own user experience is appreciated!

thanks!
