It depends. Heavy setup offers more stats for the user who has the physical strength to maintain speed of movement. But with age and joint issues, players go for lighter setups, trying to compensate for the negatives with experience.
It is something else for the EJ, who always have some TT package for delivery. There is no fixed setup, but bouncing between many. The perfect weight is changing from the combination of blade and rubbers. Weight is not the only factor. For example, a 5g heavier blade (from the same model) adds speed and rigidity that can make the setup better or worse, depending of the player. And that is not coming directly from increased weight. But switching to 20g heavier rubber makes every move slower and the setup head heavy. In my late teens, after injury, I made a calculation that just 7g more on the tip of the racket, needs 20% more force for acceleration in the wrist. And I started to trim some blades... but that is another story.
The lighter setup is easy but can lose some stability from the lower weight and from the lighter blade. Such blades (<80g) have trade-offs - smaller sweet spot, too flexible, too slow, etc. Personally, I prefer a setup of 180g, enough for stability and for quick wrist movements. Unfortunately, I really like to play with my two heaviest blades (101 and 108g). My EJ virus is still strong, and I am just trying to keep the weight below 200g with some compromises in the rubber department.
