I find the build quality quite poor, for example, there's quite a lot of 'wobble' between the lens tubes. Not so much of an issue with AF, but very frustrating with MF. I also find it very difficult to get sharp images.
My 18-55 has no wobble whatsoever. If yours seems excessive, it could be broken, which could cause a lack of sharpness, as well.
This lens grades out as "very sharp" and beats a long list of much more expensive glass in reviews. MF is horrible with any rotating front element, but as long as your post-work is decent, the current IS version of the 18-55 should be quite satisfactory, if not excellent.

Go with the 18 55 for versatility but u can't beat the sharpness of the nifty 50 and great boka
And Dof. I was very impressed with the sharpness and IQ from my 50 the 18 55 just doesn't compare in IQ
The nifty has notoriously poor bokeh (although all bokeh is subject to personal taste) because of the small number of blades used in its aperture. The 18-55 IS is also very, very close to the nifty when it comes to being capable of producing very sharp images.
I stand by my suggestion. The 18-55 is better built, more versatile and capable of everything the nifty is, short of shooting at a very wide aperture.
