I'm not sure which Switchcraft connectors you're referring to, but the A3F and A3Ms were pretty much an industry standard for a long, long time. They were so much better than the true Cannon XLR-3 connectors they displaced that there was no comparison, IMO, if only because there weren't any tiny loose screws to get lost. A great thing about Neutrik as a company is that they listen to end-users and implement incremental improvements, something that Switchcraft and Cannon never seemed to see the value of. I switched over to Neutrik XLRs ages ago, but I still have scores of cables terminated with Switchcraft connectors that have given literally decades of dependable service, so I don't get the dissatisfaction with Switchcraft.
