I have owned and shot Vortex PST's/Razors, Leupold Mk 4's, Nightforce NXS/ATACR, and a Steiner T5Xi. Hands down the best is the Steiner, I'll get to that in a minute. Here's my honest opinion since you don't really have a budget ( a good thing
)
Vortex PST's and Gen 1 Razors have decent glass, but they milk out and lose clarity at their top of the magnification range. I'm not a fan of the PST and Gen 1 Razor turrets, but that's all personal preference. The Gen 2 Razor is a GREAT scope, but it comes with a 3lb weight penalty. If you're building a match rifle, its irrelevant but too heavy for a hunting rifle IMO. They come with a good warranty, but they're made in China and I've seen several need to go back in and/or replaced. Last thing I want before I pull the trigger is the thought of "is my scope tracking right?"
Leupold Mk 4 30mm scopes have better glass than the Vortex (except Gen 2 Razors). The reticle thickness is too bold for my liking, but if you have bad eyes that might be a plus. The biggest problem with the Mk4 scopes is the turrets. They track well and have crisp audible clicks, but they aren't MIL turrets to match the MIL reticles they put in the scopes. They offer the MK4's with M5 turrets, which are MIL turrets. Not having matching turrets and reticle subtensions in long rang shooting is a crime. Unless you're really good at converting MILs to MOA, or like to get easily confused.
Nightforce NXS is an all around good 30mm scope. Several options on how to conform the turrets (high speed/non HS, zero stop/non ZS) and PLENTY of reticle options. For an MOA reticle the best IMO is the MOAR or NPR1. I also like the MIL-R reticle. Good clarity and track perfectly. Known for being durable, I've dropped my rifle before onto the scope on a rocky surface. Picked it up and got a first round hit on a target at 1380 yards. If you want better glass and a 34mm tube the ATACR is a clear upgrade form the NXS. Noticeably better clarity, brightness, and more internal elevation adjustment. Can be had new for $1900-2000.
Lastly, and my favorite scope for under $2000 (I paid $1600) is the Steiner T5Xi. I run a 5-25x56 on my rifles. 34mm tube and only weighs 2 lbs. Glass is on par with the NF ATACR for $400 less (German made scope). Very generous eye relief for shooting odd postitons and not getting scoped, as well as easy parallax focus. Very low profile turrets with clear adjustment clicks and great fit/finish. Eleven illumination settings with off positions between settings. Zerostop on the turrets is solid and the easier to set than any I've done before. One of the best features is the turrets "roll over" at 12 mils so you never have to guess what revolution of the turret youre one. Your turrets read 1-23 MILS, even past the first revolution. Then it rolls back over when you turn down below 12 mils again. VERY useful in high stress situations. A bonus with the Steiner as well, is the free magnification throw lever and Tenebraex flip up scope covers after filling out an online review through the Steiner website, mine took about 2 weeks to show up in the mail. I have been trying to find something I don't like about the scope because I like to switch gear a lot
but I can't.
Hope that helps a bit. I'm in no way affiliated with any scope manufacturer. Now if you want to spend $3000, the doors open up to a whole new world of elite scopes.
