The 4700 is the same SAEC 407-23 model and any of those tonearm manufacturers you named could envy the SAEC quality building levels.
Btw, the SME 3012 tonearm uses that same " archaic " anti-skate mechanism and I have to say works really fine but I name the 3012 because in the last 2 years is considered byt top system audiophiles as one if not the best tonearm out there.
Tango is a Thailand based audiophile whom own not one but 3 American Sound TTs where has mounted around 8 tonearms 3 are the 50K+ SAT and 3 the " archaic " SME 3012. He owns several cartridges as: Goldfinger Statement, Opus 1, top VDH, Etsuro and the like and you know what: he prefers the 3012 over the SAT ! ! ( I think his sytem is over 500K+ easily. )
