From a tech point of view, the 3.0 turbo has a lot going for it. Stronger rods, fully fined cylinders, bigger exhaust ports, better front to rear balance with the short transmission, lighter clutch pac and no intercooler, lighter rotating weight with 20mm 911S rotors and usually 15" rims. They also had a WUR design that provided acceleration enrichment fuel sooner.
Also, potentially less sensitivity to detonation with the smaller diameter combustion chamber, shorter stroke, and lower compression.
Many of the 76's did not have the power brake and still had the through the front trunk sway bar.
However, it also had a ridiculously poor design of the headers/heat exchangers.
I would have a hard time choosing between the two.
