As long as you nail the focus..I agree..
I haven't shot it wide open, really, but I'm not detecting any front/back-focus issues at apertures I typically use and so far no discernible chromatic aberration either, which is nice. I was really surprised to find Adobe Camera Raw has a distortion correction profile for this lens as well so, yeah, color me one happy camper!
Thank you for your previous reassurances, by the way, while I was waiting on delivery...
