I currently ride both. I can't think of a problem I've ever had with the Paselas, while sadly I have sliced open a Gravelking descending a rocky hill during the first 5 miles of Eroica California. I chalk it up to bad luck and so-so skills, but I also think the Gravelkings are a little more supple, a little softer. If you're not charging harder than conditions permit like I was, you'll be fine with either. In the end I've used a strip of tyvek and rubber cement and still run the Gravelking tire with that 3/4" slice, problem free since that once incident. The other 6 Pasela tires on my bikes... yeah, I can't remember when I've had a flat. I probably need to ride more!
