From left to right - Uniball air (roller/ball), Click orion BB nib, Scrikss metropolis 78 with Kanwrite M nib, Pelikan Jazz M nib, Jinhao 911 F nib.

• Click orion is a favorite. Nice ergonomics, wet writer, juicy BB nib [Click].
• Scrikss fountain pen - I am now using this pen with Kanwrite M nib now (original scriss nib was good too; it just got transplanted into some other pen during experimenting with nib-swaps). I like everything about this pen, except the fact that the cap is a bit too tight to pull-off. I have been using this pen for several years, and the cap has become a bit less tight over time. Otherwise, it is sturdy, comfortable to write, and has an elegant design.
• Pelikan Jazz - The nib is buttery smooth; a delight to write. However, the section/body junction becomes loose while writing, and will need to manually tighten it. I plan to use an o-ring to hold it in tight grip.
• Jinhao 911 - a wonderful pen. Easy to quickly pull off the cap and write without unscrewing. Wet fine lines, never skips. This particular jinhao 911 has been kept inked continuously for several months now.

The slimmest pen on the bottom, in the first image is a very smooth wet writer.
I especially like the pull-cap models (first couple of pens, top, first image).
Kanwrite desire had no. 5 nib-pens earlier (2nd image). I find the no.5 nib desire much more ergonomic to hold and write (just personal preference).
