What are the advantages and disadvantages of the penholder grip?

Hello I am a teenager but I have used the penhold grip for almost 3 years not and would like to correct the person responsible for stating the disadvantages of the penhold grip. This is an updated version of the REVERSE penhold grip (using other side of paddle as backhand).

Advantages: Strong quick smash attacks on both backhand(I use penhold reverse grip) and forehand. I agree with the following: it is almost impossible to jam a penholder. It is easy to mask the type of return stroke planned with the penholder grip, which makes it difficult for the opponent to anticipate what type of return to expect. The penholder grip allows for excellent ball control.

Disadvantages: Tiny bit of range is lost and the grip is awkward for new players, and requires practice to perfect. Other than that it has none others!!!

The penholder grip is popular in Asia. With the penholder grip, the index finger and thumb are held around the handle of the padde, with the wide blade of the paddle facing down.

Advantages: The paddle always faces the same direction, so one does not have to switch paddle sides from a forehand to backhand shot. As a result, it is almost impossible to jam a penholder. It is easy to mask the type of return stroke planned with the penholder grip, which makes it difficult for the opponent to anticipate what type of return to expect. The penholder grip allows for excellent ball control.

Disadvantages: The grip is awkward for new players, and requires practice to perfect. A slight amount of range is lost for the penholder, as the paddle is held near the middle of the handle, instead of the end. It is difficult to smash the ball as hard as with other holds, because the penholder stroke always comes from an underhand position. Backhand smashes are particularly difficult.
