the 0's have proven to me a better ride overall, equal reliability, slightly better traction in the dry/hot environment. The 0's might not net as high of mileage if ridden in the warmer/hot climate more frequently, but IMO, I'd rather have better traction overall tire life.
The above has been based on my experience & is comparing GP5000 to Velo 4S, Race, & P7
