A question on 180 vs 192: which is best?

I mean:
-was 180 the best in the pre-emission days and thereby best for engines like most of ours, and the 192 arrived as part of emissions package?
or
-is 192 best for the engine and 180 is only used on engines with cooling issues (thereby compensating for a problem somewhere else)?

By "best" I mean which temperature is best for performance, fuel economy and engine life? Should a Pantera with no cooling issues use a 192 thermostat?

My boat engines run cooler thermostats for safety and salt water crystallization reasons, and that's well known to reduce performance and fuel economy

Just wondering...
