Clean line art, Lazy Nezumi, Photoshop line art and Manga studio inking, which is best?

Something I know a lot of people wonder when it comes to digital painting / working on a graphics tablet ( including myself ) is how to get clean line art, by that I mean smooth lines that are not all over the place. If you have used a graphics tablet before you will probably know, slow careful line work usually looks very shaky due to graphics tablets being so sensitive. So the general advice here is long fast stroke to get a smooth line, and to be fair, it does work!

That being said I work in Photoshop CS6 and I have to say my line work and inking is absolutely terrible. I had heard of a program called Lazy Nezumi which works with Photoshop to smooth your lines, it has many presets with the option to adjust the settings. I will admit I haven't played around with the settings yet but I made a quick video with my initial thoughts and the results of the line art too. I think the program works but aside from the string pull option it didn't do as much as I was hoping - see the video below -

After making this video I decided to use the same image to make a comparison between Photoshop and Manga studio for line art. Photoshop CS6 VS Manga Studio 5 to be exact, and I think the results are pretty impressive, I will definitely be using Manga studio over Photoshop for inking and clean line art from now on. In Manga studio I used the G pen for inking, works really well with a pressure sensitive tablet and is great for varying your line weight too. I have also heard that in comparison with Photoshop, Paint tool SAI and Corel Painter are pretty good, I haven't tested that yet though.
Anyway.. I have posted a video comparison of Manga studio Vs Photoshop for line art so be sure to check it out and let me know what you think to the results :)
