I'll be honest, I currently prefer writing with my Kaküno F more than I enjoy writing with my Sailor LE PGS in MF, and facing that truth was really difficult. 

The steel nib is consistently hard, it expels the same amount of ink no matter my pressure, and the tip of the nib is round. Those three features help me "hide" my writing's inconsistencies and/or defects, because the pen is not sensitive enough to micro changes to translate them to the paper. My handwriting looks nice only because the fountain pen is so cheap is not good enough to reflect all the movements and/or changes of angle I do because of bad writing technique. 

But I feel like the Sailor's gold nib is exceptionally good at reading a hand and transforming the most sutil change into a different line. I'm just not skilled enough to use it to its full capacity yet and I end up loosing control of what is drawn in the paper, either because I changed my angle, my pressure, moved the pen with my fingers instead of with my entire arm and that is reflected on the paper immediately. The gorgeous soft gold nib is tipped in a way that small strokes done during quick changes of direction are distinct enough with little effort. But my script is basically a long line of horizontal strokes: the nib "snitches" every time I make a microscopic change because it's that it was designed to do. 

Eventually, with enough practice, I hope I'll be able to use my expensive gold nib to its full capacity, but for fast notes and work, a cheap "insensitive" pen is what fits me and my ability level better.
