Which turntable should I keep?

[nailer]

The Thorens would be my choice.

At this point, anything with circuit boards and caps is just a complicated failure waiting to happen. I’d keep the tables with the least complicated drive systems

I find that needlessly alarmist. We've been living with electronic circuits in our daily life for many decades now. People are still running turntables from the earliest days of direct drive models. Those circuits, apparently about to fail at any moment, have shown themselves to be rather reliable, and turntables are about the longest-running electronic devices out there. Many people still routinely own and operate 50-year old electronic turntables, and the idea that the most basic belt drive or idlers are automatically better is suspect. Certainly simple design has its virtues, but it is merely a different philosophy, neither better nor worse. The electronics do bring benefits, too, which is why people continue to use them. There's no real reason why a turntable must be a yogurt-pot-and-string affair, any more than any other electrical device.

Depending on condition and on which you like listening to... all other things being equal I would keep the Thorens and the Kyocera. Hope that helps.
