Tow mode vs smart

When I was towing my 4000lb trailer with the 2023 palisade limited I put it on a smart mode and it seemed to get better handling and mileage than when I was putting it on tow mode ...is thus true for anyone else? I also could hear my engine revving harder and louder when I stepped on the gas when in tow mode but not smart mode...so is smart mode better for towing?
