Pasteing here from another thread:
VS is sturdier and stiffer, noticeably more mass in the throat and shoulders, so that its tip seems too light, it was made for pro use, made to add a lot of lead at 12, and then it feels balanced. VS has that ridiculous energy return too, if you flatten a forehand and nicely connect it's a projectile. PA98 still gives nice generous power, but not like that, PA98 has a bit more flex, less punch and less energy return. VS is rock solid, like RF97A, Yonex VCP 330g or Rad Pro G360+, while PA98 can slightly vibrate on some flat shots, but nothing much, like most good racquets for advanced players.
PA98 is noticeably smoother and more linear over the whole stringbed, not just the sweetspot like VS. Significantly lighter and less stiff/sturdy in the throat and shoulders, its mass is more evenly distributed, whereas the VS is very depolarized. PA98 has higher sw, noticeably more mass at the tip of the racquet. PA98 is stock just like I have my VSes modded, with 2-3g of lead at 12. PA98 reminds of Radical MP in terms of weight and flex distribution, but gives more power.
With both VS with lead and PA98 stock, same-ish sw, VS needs constant superfast hitting and crucially attacking the ball in front of the body, it feels good in fast rallys. PA98 is way more forgiving in that sense, you can dig yourself out of the corner with it more naturally and easily, it'll also work great in faster but not fastest ball exchanges, and it doesn't need lead at all. You can swipe at the ball slightly late with it, that works a bit better with PA98, defensive or grinding points sometimes too.
Simply put, VS is (too) stiff, and too demanding, made for people who play Futures level and up, and who hit the ball 4h daily, with fresh strings. It's a race car. Babolat made it for Alcaraz, and we'll see many other pros play with it over the years, painted in PA98 colours.
PA98 is for everyone else, your arm won't fall off, you lose some of the punch and stability, but not that much if you're not a hard hitter always looking to flatten the ball and punch through. PA98 is easier to use than VS, and I think a lot of people will really like it. A defensive counterpuncher or a grinder won't like it all that much though, as it will still ask to attack the ball consistently, with a nice long full swing, and a lot of energy, not just a snowflake
