I have had many Vortex optics, especially their rifle scopes. I love them- the glass is superb. I have traded out my Leupold and several Nikons for Vortex and they're all I've purchased for several years- and all I plan on purchasing unless a need for a scope in specs they don't make comes up.
I have two Vipers (both lower magnification and smaller tube than the one you are looking at), a Viper HS, and a Razor HD as well as some binos and a reflex sight. The adjustments on all of the scopes, including the less expensive Vipers, are very tactile and tracking is consistent. From the perspective of someone who has sold a ton of optics of brands from Tasco and bsa through Leica and Zeiss, I can say the Vortex warranty is amazing. They really do stand behind their scopes and I've seen the "no fault" part in action and was incredibly impressed. I've seen other "lifetime warranties" that are a joke as the company will find a way to blame the customer for any issues.
In my personal opinion, a Vortex scope is always a fantastic choice and all of the models I have personal experience with far exceed their price point in terms of quality. I prefer Vortex to Leupold very strongly- comparing models within the same price point from the bottom to the top of each line, I have been really impressed with the clarity of the Vortex as well as the user-friendliness.
I personally like the reticle, as I have a strong preference for simple, easy to read reticles with duplex style wires... I typically gravitate towards mil-dots and the like. That said, most of my shooting is hunting inside of 300 yards and I rarely do any kind of stationary target shooting and after my seasonly sight-in I pretty much rely on kentucky windage to make my shots, which may not be what you're looking for.
I'd say try to get your hands on a similar scope in a local shop and see what you think! Everyone's eyes perceive clarity differently and everyone has preferences in terms of adjustments and reticles, but based on all of my experiences the quality of the optics and the customer care of Vortex is totally fabulous.
