Tamiya's are the oldest, but the turret was retooled circa 1988-89 and is very nice. Hull is still basically the same motorized-capable one from the 1970s though. The Tamiya M60A3 kit is due to be reissued this year. It builds into either an M60A3TTS or an M60A1 RISE/Passive tank.
Tamiya's USMC M60A1 RISE/Passive with ERA is basically the 1988-89 M60A3 kit with new ERA armor, new steel road wheels and figures. You can still make a US Army M60A3TTS tank from what you get in the USMC M60A1 kit. The Marines did use this tank during ODS as well as used a few hand-me-down M60A3TTS tanks from the Army. The 197th Separate Infantry Bde brought A3s with them and got M1A1s in theater. The Marines took some of the A3s for the thermal sight capability and used them in combat.
The Esci/AMT/Ertl kits from the late 80s are the same kits that Italeri and Revell reissued in the 2000s with a few tweaks. They are the best kits to make the most accurate M60-series tanks from. The original Esci/AMT/Ertl kits came in three variants; the M60A3TTS that could only be made into a US Army tank, the M60A1 which could be made into a garden variety mid-M60A1 and the Israeli M60A1 with Blazer armor. It was the same as the standard M60A1 with Blazer armor and IDF specific fittings added. Note that none of the three kits would produce an ODS era US M60A1 RISE/Passive straight OOB.
The reissues had some differences. I did an article on the Esci/AMT/Ertl kits a while back.
Revell released the M60A3TTS tank as pretty much a straight reissue with a few additional parts.
Italeri released the M60A1 as a straight reissue as well.
But when Italeri reissued the M60A1 Blazer kit, they removed the items that could make the kit a standard M60A1 (mainly the plain gun tube and commander's cupola parts).
I've never been fond of Academy's M60 series. They borrowed a lot from Tamiya's original kit, to include all the motorization holes. They also had separate rubber rims for the road wheels which I did not like.
If I was to make a tricked out ODS USMC M60A1 RISE/Passive tank, I'd grab the Tamiya USMC M60A1 RISE/Passive tank with ERA and use the armor, turret, late style air cleaners, and any Marine-specific fittings on which ever Esci/AMT/Ertl/Italeri/Revell hull I could get my hands on.
Gunze Sangyo produced an ODS USMC M60A1 RISE/Passive tank with ERA that was basically the original Esci M60A1 kit with their own ERA pieces and some resin included. If you remember my note above that none of the original Esci kits builds into a RISE/Passive tank OOB, Gunze Sangyo missed the mark by a little bit but charged you a hefty price tag for their kit.
