You guys and your fancy fountain pens. XD
3 functions in 1 pen is good enough for me: red correction ink, note-taking black ink, small-handwriting 0.5 mm mechanical pencil. With a fountain pen you're limited to, essentially, one ink colour, fat writing tip, and paper bleeding unless you buy special paper.
Functionality for the win.
Terrible up-close iPhone photos for the win.
Red + Blue + Black pen on mine. Didn't feel like buying the 5-way pen since other colors are unconventional.
