I myself have been overall happy with using Lightroom sharpening if my output is for the Web and personal use or "sharing" with others for viewing and whatnot. I'll use the Lightroom "input" sharpening to taste (fine details, viewed at 100%) and then I'm pretty happy with the screen "standard" Output sharpening when Exporting. Note that when people mention that they use ACR (not Lightroom) they have the same input sharpening tools as Lightroom and can, if they wish, use the Export function with the Output sharpening tools as well. Photoshop does provide those capabilities with recent versions.
The question arises as to when other steps may be desirable. I have done some "selective" sharpening using the Lightroom adjustment brushes, it has come in handy with, for example, wildlife shots where I want to optimize detail in the critters while keeping the background softer or even softening it with a brush.
Doing special "output sharpening" in Photoshop is, well, a choice, and not something I've really jumped into, but I may consider it if I wade into doing more large prints...that is, prints that will get a viewing that will benefit from "touches" that Lightroom may not suffice, I'm not sure because for the photos I take and the way they are "shared" I just haven't seen the need!
