I had the need for a sfp scope with illumination, and given the fact that the new Gen 2 Midas BTR is available with an attractive & useful mil reticle, I bought two of the 4.5-27x50s. I've really enjoyed shooting behind Midas TAC 6-24x50s on a couple of 22RF repeaters & two of my Howa Mini rifles (the other two Minis have Gen 1 Ares BTRs on them, and I find myself wishing I could swap 'em out for either Gen 2 Ares or Midas TACs).
Reason I wanted a sfp scope was because I wind up out & about both early in the morning & late at night with a rifle, watching over my little 34lb Aussie shepard/border collie cross while she does her business, and the ffp reticle of the Midas TAC at 8x is too hard for me to see with a flashlight, while the Gen 2 Midas mil reticle is perfect for this application, especially with illum set on #1 or #2. The dot aiming point is noticeably larger in dia than any of the other aiming point dots on the Ares ETR, Midas TAC, Ares Gen 2, or even the newer Cronus, which is something I appreciate. I had a Midas TAC 6-24x50 on the V22 sporter, which was replaced by the Gen 2 Midas BTR. They're both mil scopes, so one of the first things I did after zeroing the new Midas BTR was to run the elevation up to 7.4 mils and shoot the V22 at a 6" gong at 200yds - dink, first shot hit, no problem. So now, I've got a scope with good glass, good clicks on turrets, good reticle, great tracking, zero stop, AND illuminated reticle that works great in the dark. Exactly what I thought I needed, and at a price appreciably less than the ffp version, yet still in mils so that all the come-ups for 22RF I've gotten accustomed to in my ffp scopes. The 2nd one is going to replace a nice little 1" Weaver 4-20x50 Super Slam on the AR15 SPR I carry in the truck, and I'm pretty darned certain I'll like the mil clicks a whole bunch better than the 1/8 MOA clicks on the Weaver.
