It depends

When you first begin it doesn’t matter if you use different golf balls. As you become more serious and want to get better, I would recommend using the same type of golf ball. I would suggest this because golf balls feel, launch, and spin differently. Using different golf balls means constantly adjusting to the firmness while trying to gauge how hard to hit a putt. Using different golf balls means adjusting to how each golf ball will spin or check on the green for short game shots. It can also change how far your golf ball goes. This is the only piece of equipment you use on every shot. Would you different clubs every time you played?
