Tennis balls look identical and play very differently. The fundamental divide is pressurised versus pressureless. Pressurised balls have a pressurised core that gives them lively bounce and crisp feel — but that pressure leaks out within weeks of opening the can, leaving them flat and dead. Pressureless balls get their bounce from a solid core, so they last for years, but feel heavier and duller. Matching the right type to matches versus practice saves money. We ranked the best by use.
Pressurised or pressureless? Use pressurised balls for matches and serious play — they offer the best, liveliest feel, but plan to replace them every few sessions as they go flat. Use pressureless balls for practice, hitting walls, and ball machines — they last for years and won’t go flat, though they feel heavier. Most players keep both.

What to skip
Using flat pressurised balls for matches. Once a can’s been open a few sessions, the balls go dead and bounce low — frustrating and unrepresentative of real play. Open a fresh can for matches; relegate old balls to practice.
Pressureless balls for serious match play. They never go flat, but their heavier, duller feel isn’t right for competitive tennis and can be tougher on the arm. Keep them for the ball machine and wall, not match day.
The wrong felt for your surface. Extra-duty felt is for hard courts (regular-duty fluffs up and wears fast there); regular-duty is for clay and indoor (extra-duty picks up clay). Match the felt to where you play.
How to choose
For matches and serious play, Penn Championship is the best-value pressurised ball, with Wilson US Open the premium pick — just replace them every few sessions. For practice, ball machines, and wall hitting, pressureless Tretorn Micro-X balls last for years and save money. Most players keep both types on hand, and match the felt (extra-duty vs regular-duty) to their court.
Store your balls and gear in a proper tennis bag, and keep your racket dialled with fresh overgrips.
