Illustrator is the best tool for vector art out there. If you want a good line tool, it is the way to go... But it will enable you to color, ink, add effects and load of other comicbooky things... with ease..
You can stoke your lines with 'realistic' brush-strokes too...
If you are really picky and want a really powerful tool that can do a lot... then do it... but if you are worried about the price.. and you already have Photoshop... use the vector lines it has.... They are harder to use, and have limited stroke options... but they are there...
