Looking at getting a scope for my Tikka T3X Tac A1. Have narrowed it down to the Cronos BTR and Vortex Razor Gen II. Athlon is ~$1100 and Vortex is $1700. Have looked through and handled the Vortex but no experience with Athlon. Is the Vortex demonstrably better for the extra $600? Looking to shoot to 1200 yards. Thank you in advance for your thoughts and experiences.
