For a rifle that would be used in the hunting fields, I think the BDC would be a large advantage. Whether for tree squirrels or ground squirrels, the small targets and loopy trajectory call for accurate hold over and the BDC just makes that dead simple. If it's mainly for range use, specific distance, or you're a "twister", then I'd go with the T-plex. This will probably be going on to my next 22 build. I don't expect the glass to be as nice as my Toric but I suspect it will exceed the quality of the last couple "rimfire" scopes that were in this price range.
