Maintenance/wear parts, with the gasser is simple.
Simplicity at its best. No turbo, no turbo moving vanes, turbo actuator, no adjusting valves at some point, no ccv filter to change, no def fluid, no anti gel when cold out, no def pump or. scr to go bad, no dpf to plug, no egr or egr parts, no glow plugs/grid heater.
Gasser, this one, has no cylinder deactivation, or start stop stuff, doesnt even have an egr, just simple.
No exhaust brake, i lived without one before my second diesel, and ill live just fine now without one.
