60 Series vs. 6V92 series newell coach ?

[Aussies]

Hi all!

My question is about engines. I'm tossed here. I am interested in 2 different coaches in 2 different era's one with the 6v92T and another with the 60 series engine. I have been told the 60 series is quiter, more fuel efficient, and is an overall higher quality engine than the 92 series.

My question is does the 60 series really outperform the 6v92 as much as I've been told?
The wife wants the more classic look and I prefer the smooth side which is why I'm stuck so hopefully we can compromise
