Rec guys might need some help with spin to go from 500rpm to 800rpm. The pros who hit with high spin maybe want a racquet that gives them a bit more control as they hit >3000 rpm anyway. Similarly a pro who hits flatter likely has laser-like precision already and maybe wants a little more spin help or extra juice on his shots. Plus you can tune a racquet‘s performance tremendously by stringing it differently with different strings, gauges and tensions. The reviews which claim particular racquets are suitable only for particular styles of play are a bit overblown anyway.
That one makes more sense than we now tend to recognise, the original brief for the pure drive was for a frame anyone could use to sell to the biggest market in tennis which is doubles, i've never seen what theirs actually were though. So by design the PD was for doubles players.
These are alternate rationales for racquet selection: against the type of player indicated by the marketing for a racquet
Racquet gives you something your technique and play style do not
Of course this really works against the typical racquet review assumptions. Racquet reviews are really kind of nonsense anyway wrt pro players. Those guys reviewing the racquets are totally different creatures from pro players.
Even upper D1 players talk about racquets in fairly different ways than the typical racquet review (or these forums).
