I decided to order an EF nib as well and put it in my Furore (which is basically the same pen as a Momento Zero, except being cigar-shaped). This way I could compare my hallowed F in my Momento Zero to the EF in the Furore. Also, I compared the EF to other "European-EF-like" nibs in my small collection: a 14k Sheaffer Targa Slim XF, a 14k Sailor Pro Gear Slim H-MF, a Kaweco Dia2 EF and a '49 De La Rue fitted with an extremely fine (as in: narrow) accountant's nib. All of these are hard nibs without bounce, whereas the Leonardo is very soft.
I compared smoothness, wetness, line width and degree of control. The Leonardo EF is by far the smoothest of the EF-like nibs I compared it to, and it offers me the greatest degree of control as well. It improves my handwriting substantially, which (to me) is a rare quality in a pen. Wetness is perfect. Line width is in the middle of my other EF-like nibs: wider than the De La Rue, just a tad wider than the Pro Gear Slim, comparable to the Sheaffer XF, narrower than the Dia2.
The only nib that comes close to the Leonardo EF is the '49 De La Rue accountant's nib. The Sheaffer XF, Kaweco EF and even the Sailor MF feel rough and crude after writing with the Leonardo EF.
After writing with it for a full week, the Leonardo EF even removes the Leonardo F from my top spot. The F is totally amazing, but the EF offers me much more control while being soft, bouncy, remarkably smooth and wet.
I'm still sort of recovering from the shock that these two simple, cheap, Bock-made steel nibs effortlessly make it to the top of the heap for me, surpassing renowned 14k and 18k nibs from other brands.
(Of course I am aware that others haven't been so lucky and have been plagued by baby's bottom and/or incorrectly cut nibs. That's unfortunate and should not have happened.)
