I've got four of the 4.5-27x50 Ares BTRs on various rifles, and feel they're well worth the money - especially at the March sale prices. Though floating dot reticles seem to be all the rage right now, I prefer the + aiming point of the BTR's reticle. The Midas TAC 6-24x50 lacks only the illuminated reticle, but goes with the floating dot, focus down to 10yd, and has a covered windage knob. I feel the glass quality of the TAC is slightly better, and the clicks on the turret knobs are definitely a step up from those of the Ares BTR.
