For a ball Machine, it does not change the kind of ball you would use if you were playing a tennis match. If you are a keen tennis player (plays more than 3/4 times per week) i wouldrecommend to buy Head ATP or any Slazenger but if you are just a typical player any unpressurised ball can be used with success.
Wilson is far better than Penn. Wilson balls keep their pressure longer and do not have a tendency to fuzz up. Penn is terrible. Penn tennis balls fuzz up really bad and they loose pressure very quickly. Actually the best tennis balls are Dunlop. They keep their pressure much longer and do not get heavy and fuzz up.
Yonex
Generally, Wilson tennis balls tend to have a longer bounce compared to Penn tennis balls. This is due to differences in the core material and design properties of each brand's tennis balls. It is recommended to try both brands and choose the one that best suits your playing style and preferences.

Rawling balls are the best

Volkl is a more expensive brand of tennis products. They claim to be the "best," and do have good reviews by people who have used the products.
