I can't compare to a vortex but I recently purchased the 4-20-50 and it seems very well made. Turrets are large and have a good feel. Glass is good but next to my luepold vx6hd the lup is brighter/cleaner imo. Tracking was perfect on sight in. I haven't had time to really play with it to much yet though. Hopefully over the holidays I can make time And will report back.
