I've had several failures with the 6-24 pst and hs. Out of the box new, with failures. Oil on internal lenses(4 scopes), reticles would rotate with power change(3scopes). The 4-16 hs's that i have or had were all decent. I still have one on a spr build. The 2.5-10x44 was a nice little scope but there was a blurriness all along the reticle, in every direction from center, that extended out past the ends of the hashes . The razor i had was good, glass was about par with my dmr and less then my swfa 5-20sshd. I have 2 dmr's and 2 5-20SS to compare to. The illumination crapped out on the razor also, but in fairness the only illuminated scope that i owned that wasn't a letdown was my nf. I would avoid the pst and hs on anything much bigger then a 308. Plenty of issues with braked 300wm and 338lm. My friends 20 lb 338lm destroyed a pst in less then 30 rds. I was doing load work ups for him and the scope started shifting poi/poa by 2-4". Took off the optic and shook it, could actually hear it rattling. Stuck a simple 6.5-20 vx3 long range on it(that loopy scope had 4-5000 rds trouble free) and finished load work plus another100 rds without issue. Vortex is very friendly and courteous for repair work. I've owned nf, leupold Burris,bushnell, SS , trijicon, and ior. All ran equally hard, the only scopes i've had to send back was vortex and some repeatedly. To be fair every manufacturer can turn out a lemon, but my experience leads me to stay away from 6-24 vortex scopes.
