It's perhaps a little unfair to lump all of one manufacturer's product against another, for instance I would take Tange Ultimate UltraStrong over Reynolds 501 and Reynolds 753 over Tange Infinity. Both produced (and still do) great tube sets, but as 24" above points out, so did (and do) Columbus and True Temper.
Snr Queso also correctly identifies the fact that a builder (quality of construction, selection of appropriate tubes, understanding of their properties will make a greatet difference than pitching one tube against another.
In my experience the high end vintage tube offerings from Reynolds and Tange make great riding bikes, but Bontrager's ride fantastic despite not having a 'high-end' tube set, it's partly down to the geometry.
FWIW, my modern MTB is Reynolds 853, my modern road bike is Reynolds 653 and my vintage MTBs are: 753 ATB; Tange Prestige; True Temper 4130; Columbus/Reynolds mix; Reynolds 531 ATB select.
