I know I'm late, but this is wrong. I have personally tested the 10x30 Yosemite against a 10x42 Vortex Diamondback, which costs
$230 (and it was a pre-2018 Diamondback, not the new HD version, which is apparently better). I did enjoy the view through the Yosemite, and for me they seemed to handle glare a bit better, but build quality was not good at all, and the Diamondback was distinctly sharper, with much better close focus. I agree that porros typically outperform roofs in the same price range, but not roofs 5x their price.
Btw, I posted my full comparison
