I'm a Thorens fan, too. I have also owned an ARXB, but liked the Thorens more. My model of choice was always the TD-165, but a TD-160 is even better. These are belt-drive tables with sub-chassis suspended on springs, thus similar in design to the AR. So if you like one, you will probably like the other. A good strategy may be to keep an eye out for both, and buy whatever/whichever you find in excellent condition.
IMO, the Thorens is the better table, having a better arm, headshell, and cuing device, and appears built better overall. The TD-165 that I love is completely manual.
Personally, if choosing an AR, I'd rather buy an AR EB101 table (built mid-80s) than either an XA or XB. It still has the right vintage look, but a bit better design, imo.
