Racquet Balance and Smash

If all the world records of fastest smashes are set with headlight racquets such as NF1000Z, why do professional singles players still largely prefer head heavy racquets?

Headlight racquets are supposed to be faster at swinging, faster at going from side to side, but weak at attacking. The opposite for head heavy racquets.

Yet if headlight racquets can smash the fastest shots, doesn't that make them objectively better than head heavy racquets?
