I hope I'm not preaching to the choir, but I assume you know that one should not / can not get the best sharpening results unless you apply a relatively small amount of initial sharpening (eg, using the "Details" tab in LR), and then again when you resize the image for final output (eg, using the "Output Sharpening" section of the Export dialog box in LR). If you try to get all the sharpening you need in one step (say, using only the "Details" section of the develop module in LR), the results will likely be less than satisfactory. This might be the problem that you encountered.
BTW, in the preceding paragraph, I gave examples based on a purely LR workflow, but the exact same principle is used if you are working in PS.
The two step sharpening approach I described above is part of a more general three step sharpening process that has become essentially the de-factor standard among pro and hi-end amateur photographers. You can read about it here:

If you are already know all about the above, just ignore the above comments and, if you feel like it, describe exactly how sharpening in LR disappoints you and/or what procedures you use in PS to obtain a better effect. For example, if you find that you often need to use the anti-shake sharpener (new in PS CC, but not yet available in LR), or if you are going to a 3rd party plugin like Focus Magic, then you certainly have a good reason to go to PS, but, IMHO, 90% of all decently shot photos don't need this and can be handled quite well (from a sharpening POV) in LR.
