Daikin single speed vs. Daikin FIT

Trying to decide between Daikin DC4SE single stage AC and DR80SN single stage furnace for $9500 vs. variable speed Daikin FIT system DC6VS and DR80TC for $12500. Both units have the same 12 year warranty.

Is the added comfort of the variable speed FIT worth the $3000 differential? Live in Atlanta.
