I had the liberty of riding both V-bolt and Cheetah Hunt in the same week.
CH had a rattle, but I felt V-bolt's was a bit more severe. If anything, V-bolt rattled like Sheikra did (and it did have a noticeable rattle).
Anyway, let's get to the comparison.
Ride-wise - CH has the edge with the zero-g roll and the pops of airtime throughout the ride. Other than that, both aren't too intense, and both have good transitions. CH's OTSRs will dig into your shoulders if you raise your hands in the air, so I don't recommend trying that too often.
Theming-wise - Verbolten takes the cake. Even though both parks reused old stations, BGW definitely pulled out all the stops while BGT sorta kept most of the good theming outside. The Cheetah Run exhibit is pretty nice although the cheetahs were sleeping when I was there. As for V-bolt, I didn't get the full effect going through V-bolt's show building (I was lucky enough to ride with the lights on), but what I've seen so far has impressed me. The floating tunnel still bugs me greatly though.
Fun factor - Both coasters are great additions and both coasters are very fun to ride. I'd put the fun factor at a draw.
Overall - Cheetah Hunt is more intense with its zero-G roll and pops of airtime, but Verbolten's theming really gives it the edge to beat out CH. Either way both parks got big winners.
