Can we talk about wet stacking in older mechanical engines vs modern common rail?

I run a shop outside of Nashville and I see this ALL the time. Older guys swear by the old mechanical diesels because you can fix them with a wrench and a screwdriver. I get that. But the wet stacking issue is REAL on them when they just idle around town. Meanwhile some of these newer common rail trucks with the right tuning barely smoke at all even sitting in traffic. I just had a customer argue with me for 20 minutes that his 12 valve does everything better even though he's getting oil dilution from idling. Am I missing something or is there a real debate here? What's your take on mechanical vs electronic for daily driving?

Man that customer sounds like every older guy I deal with, they'll defend those 12 valves to the death.

And nobody talks about how those old 12 valves actually got worse fuel mileage than people remember.
