Not sure what you mean by "nicer". And it wouldn't necessarily give you a "better" photo, perhaps shaper maybe. Lenses would be rated on various measurements:
2. flat focus plane, not spherical
3. even illumination across field (no vignetting)
4. distortion or colour aberrations
5. extra features, like focusing speed, image-stabilization, etc.
With film SLR cameras, since the film can be equal across different cameras, it's the lenses that would show variations. However, with D-SLRs, the sensor and its processor also makes a HUGE difference. The Canon D-SLRs for example have a superior sensor+processor to Nikon when it comes to low-light sensitivity where the Nikons tend to show more noise and colour aberrations in the shadows.
I'm not really sure what your question is about, how about being more specific. Perhaps posting a sample photo or two.
BTW - personally, none of my "great" photos have ever been achieved with a simple click. They often took hours to set up lighting and sets. Composing the shot with adjusting focus & exposure options can take a while as well. And always required processing and touch-up afterwards, film or digital.
