I don't care for boutique reticles, and the utility of BDC knobs escapes me. I prefer to use the basic mil-dot system, or a refinement of it, because accurate ranging can be done with that system out to 1000 yards with some learned skills. Taking time to learn the Mil ranging system is worth the effort.
Another good reason is the mil system is the same regardless or manufacturer, so once you learn the system, you don't have to remember differences from scope to scope. When using a range finder, a basic crosshair is fine.
Whether using just a standard plex reticle, or mil reticle, elevation changes are controlled by the clicks or marks on the elevation dial. That works for every load, every rifle, every caliber by using different click values. I am not going to carry around a bag of knobs for every load I have...I tend to lose little gizmos, and it's simpler for me not to have to think about several different systems. I can't imagine keeping track of a bag of knobs for every scope I have, I would rather spend my time shooting.
A good warranty is important, I tend to like scopes that don't tend to break down a lot and need to use their warranty, so if I have some money in my pockets, I like Nightforce...if not I have had good results with Bushnell 6500, 4200 3-12 Tactical, that's a new model, 3200 10x, Sightron, 10x Super Sniper or the 3-9 version, Premier...the new Vortex PST looks promising if they ever decide to quit marketing and manufacture them.
