I've used a leup. VXIII 4.5-14x40 with Varmint ret. for about three years now and I find it's excellent and I only know of one other person that uses the same scope.
Scopes IMO are far more difficult things to choose for HFT as each individual is different and may or may not get on with certain scopes that others do. Horses for courses!
PS buy a Leup
