The 2021 Pro V1X has a better flight pattern due to its new layer construction. This means that the ball will launch higher and have a lower spin rate, which is important for tour players. The 2019 version of the Pro V1X was designed with feedback from tour players in mind, but it wasn’t quite what they were looking for out on the course.
I've always liked the x more during cold or wet weather (needing more carry versus roll, less spin off irons) while the pro v is better for me when it's firmer or faster. Ironically the inforgraph linked in another comment doesn't fit my iron spin experience. I do find the x firmer and pro v softer, as a scratch player
The results showed that the Pro V1 delivers lower long game spin than the Pro V1x. Like the ball speed test, the difference was minimal off the tee, with the classic Pro V bagging the title by 40 rpm. Furthermore, the Pro V1 overshadowed its relative with an iron in hand, producing over 500 rpm more spin than the x. Posted April 5, 2022. ProV1X- Firm, high launch, high spin. Chrome Soft X- Softer than V1X and BX but firmer than BXS, lower launch than V1X and BX while similar to BXS, high spin. Tour BXS- Softest of the four, similar launch to CSX, most spin. Tour BX- Similar firmess and launch to V1X but perhaps slightly less spin.
Optimized Spin and Increased ball speed with the new faster high-flex casing layer. This highly-resilient high-speed ionomer was developed initially for the Pro V1x and reduces long game spin. Softer Cover for more greenside spin and control. The new softer cast urethane elastomer cover is the softest ever used on a Pro V1 ball.
Soft Feel. The new 2019 Pro V1x has also been reengineered to be faster from core to cover. Compared to Pro V1, Pro V1x will fly higher and achieve peak height farther downrange. This results in greater carry distance, a steeper angle of descent and less roll than Pro V1. Pro V1x will also have a slightly firmer feel than Pro V1.
