In my high school we had ancient (even then) King 'glass souzys. Never a problem with anything you described. The worst I ever saw was the solder let loose on one bell screw, and when I took it in, thinking I had broken it and would therefore have to pay for it, the tech said it had insufficient solder on it in the first place, and the school picked up the tab.
I play in a community band that meets in a regional junior high school band room. Three ancient 'glass souzys hang on the wall: two Kings and a Martin. The lacquer is long gone from what appears to be 40 years of normal wear. But all slides work, all valves work, and there are no problems. I've even used one for rehearsal when mine was in the shop. No problems at all with anything you describe.
OTOH, the techs in my area tell me that Yammy valves on all of their brass are in the shop more often than all other brands combined, and I have watched students deal with the frustrations of spinning valves.
Jupiters, unless something has changed in the last couple of years, are no better. Before one rehearsal a few, and I mean only a few years ago, I got to my other community band sponsored by a regional university early, and they were unloading a brand new shipment of Jupiter brass souzys. These were faculty, staff, crew and students who knew what they were doing. In spite of this, I watched the metal dent simply from the slight hand pressure needed to lift the souzys out of the packing crates, and they sounded blatty as hell when I heard them played. The only thing that could tame about half of the blat was a really deep mouthpiece like a Schilke H-II or such. The 24AW clone mouthpieces that came with the souzys were trash.
Respectfully, I completely disagree with your generalization. My comments are the summation of decades of observed incidents, and I stand by my opinions as based on empirical observation and experience of playing souzys for 39 years.
