Perhaps they all share similar synth engine. I don't know much about 
PT... VL is familiar to me through the records of Bill Nelson in the 
80's... 
Earlier models of MT (and PT) seem to have analog drums with analog filter, 
which is an attractive feature to me.

I recently saw a PSS-470 in an auction in Japanese site. Many people 
wanted to buy 470 and at last it was sold at $80 or so. I too wanted 
to get it, but I managed to stop myself, as I've already got TG33, which 
shares 2 operator FM engine. But MIDIed mini-keys and 680's symphonic 
effect are also attractive...
