According to the spec sheet, the 6SU7 was designed for better balance between sections. If both sections are cascaded, it probably doesn't make any difference. As an LTP with active tail loading, maybe the 'SU7 will show less DC offset, but otherwise, not any great difference there either.
It might be more critical if used as a floating paraphase, or with passive tail loads.
