Our mini-splits produce much colder air than our central unit in summer and much warmer air in winter. When the central unit is blowing $$$ luke warm air in winter, the minis are producing pleasantly warm air. No contest.
What you forgot to mention is that central systems are less efficient as well as they both need more powerful blower motors to get air flowing through the ducts and plus much of the space inside the ducts and not the room gets conditioned so it's even further efficiency loss. Also, ducts can get incredibly dusty over time and cleaning those can be costly and a pain in the a$$
Yeah but you're talking a single 1/2 hp motor for the blower. How many fractional hp motors does a home with multiple heads on a single condenser or multi condensers outside? Central uses 1 blower motor, one condenser motor and one coil fan motor. A multi zoned mini split has one blower motor per head unit and two motors per condensing unit. If you have two ductless splits, that's six fractional motors.
I would always recommend mini splits for residential. Central Units for commercial buildings and highrise buildings(commercial and residential)
