I'd lean towards a Technics rather than a Pioneer. Technics was known for their turntables, especially direct drive models, and many purchased them regardless of the brands of the rest of their equipment. Perhaps less-so for Pioneer. There's nothing technical that would preclude one brand over the other .... just avoidance of a 'hodge-podge' of equipment.
I have a SL-1210 Mk2 and I've had SL-1401, SL-1700, SL-1300, SL-1500 Mk2, SL-1800, SL-1800 Mk2, etc. All good. A few well-known issues here and there, none of which are really show-stoppers. For me, I think the sweet spot would be a SL-1700 Mk2. It really is pretty-much a semi-automatic version of the SL-1210, with suspension and without the 'DJ-look' (which many don't really like). Basically same motor and Quartz-lock speed control, same tonearm (with height adjustment), etc. and capable of taking many of the mods developed for the SL-1200 /1210.
My SL-1210 sported a modded Rega tonearm up until a couple months ago. I'm putting the original back on with upgraded tonearm wiring, interconnects, fluid damper, external power supply, etc. (when I get back to it!).
