Which Tires are Better HPI B15-40 or Proline V-Rage

Hey, I was planning to buy new tires, and I came across these two. Can anyone please tell me which of these tire is better for racing, like max grip road racing. Because right now I am running on immesnly worn V-Rages and when I turn at high speeds the car just slides and spins. I seriously dont want any of that. Thing is, at accleration they give pretty damn good grip for being worn out.Then I saw HPI's B15-40 Belted Slicks tires and on their site it said they have Maximum grip with a good life span. The V Rages before I wore them out were amazing also. So which one is btter, Proline V Rage Tires or the HPI B15-40 Belted Slicks. Thankss

My V-rages pretty much only lasted a couple of days at the track. I was running B15-40s before that and didn't notice any difference in performance. I've since gone back to B15-40s. This of course is just my opinion, with my driving style, at my local track.
