How good is a fully upgraded Technics SL-1210mk2 compared to other high end TT?

As the title says;

How good is a fully modified Techy 12xx, with say new PSU, MN Bearing, ETP platter, Isonoe Feet, new arm (Jelco 750D or Origin Live Silver or Funk Firm)…

compared to say:

Linn LP12

JR Transrotor ZET-1

Rega RP8 with Apheta cartridge

VPI Classic

Michell GyroDeck

Michell Orbe SE

Avid Diva

ProJect RPM-10.1



ALL of these TT obove will cost about the same as a fully modified Technics deck.

My upgrades so far has been relatively low cost (KAB Fluid Damper, Mains PSU, Achromat 1200, Isonoe). The three next upgrades will be high cost upgrades:
- Mike New Bearing.
- Mike New ETP platter
- Origin Live Silver/ Jelco 750D tonearm/ FX arm

I was hoping that someone that has heard or own a fully upgraded 12xx, and compared it to or upgraded it to another high end TT could share som input. Hopefully compared it to one of the above.

Here is a picture of the German made JR Trans Rotor ZET-1:
