I'm not sure if the Freedom Rimfire has the same turrets as the rest of the Freedom line, but my rimfire VX-Freedom has cheap plastic turrets with horrible feel and hard to turn. VX-3HD all day for the turret feel and probably small increase in light gathering or low light performance. I have a VX-3 and both scopes look great during the day, but I have not had the Freedom out at twilight yet. The VX-3 50mm objective gathers light very well after sunset.
My opinion is the VX-3 is worth the upgrade over the Freedom. And I like the VX-3 line for simple, no frills, set and forget hunting scopes. I only have one, but wouldn't mind getting another down the road, probably second hand to save $$. Seen Vx-3 duplex scopes sold under $400 recently.
I have to agree with the wisdom that most scopes look good in bright light. But it can be difficult to test glass quality before buying. I still don't think I can appreciate the differences. I don't have experience with alpha glass, but from old VariX-II, VX-Freedom, SWFA HD glass, Vortex Razor LHT, to Zeis Diavari, all looked "good" in broad daylight or indoors. Though my VX3 4.5-14x50 does very well after sundown.
