Sorry for necro-writing in an old topic, but I just can't look at that:

I'm not an artist, but before joining this site to share tips I did a lot of research into the world of digital art and a lot of that was comparisons between programs.
From what I saw was that Photoshop isn't good.
I am sorry my dear, but you are talking bullshit. Photoshop is one of the most powerful and best raster programs. And I know what I'm talking about, I've been learning to digital paint for a few years.
For the problem stated here:
I agree that inking may be done in other programs, but it's easy in PS too. First step: go to Window>brushes. You will see brush settings. Choose round hard brush. Choose the size. Have only the shape dynamics box checked. Choose the minimum size there. Leave your brush at 100% opacity and flow. Now check how it works. It may be too hard or too sensitive. I find settings I use for painting too hard for inking. Go to your tablet settings and adjust pressure sensitivity.
Hint: If your hand is not stable work with a large zoom. In many programs you can have two windows for one image open, make one zoomed out and another, the one you're working on, zoomed in, even up to 300% (depending on the size you're working on).
Apart from that my program of choice for inking is Mangastuduo :D It's got one of the best engines for that. Also Opencanvas and Comicworks (I guess it's the same base). Painters pens are nice too, but Painter itself is quite a hassle to do.
