It's just whatever you're comfortable with. I had some head racquets for a while, they have a rectangular grip, and you get used to it. It feels nice on serve, ok on forehands, and strange on a one handed backhand, in my opinion. If you have a 2 handed backhand, it will probably not bother you.
ATP: Topspin is OP. Devs please nerf.
My Tennis: My serve has too much topspin and my forehand not enough.
