The nibs on the Platinum Balance are slightly bouncy, in a way that the Plaisir/Preppy nibs aren't. The Balance has a (pretty good) plastic body, while the Plaisir is made of aluminium, so the weight and balance of the pens are different from each other. On the whole, I think the Plaisir/Preppy Fine(03) nibs leave marginally thicker lines with marginally less feedback than the Fine nibs on the Balance.
This is from test-writing on the same sheet of paper with three F-nibbed Platinum Balance pens, three F-nibbed Plaisir/Preppy and two EF-nibbed Plaisir/Preppy pens, all with different inks. At those narrow line widths, the choice of ink can make a noticeable difference, of course.
Pretending that all fountain pen collectors and/or enthusiasts here are like-minded, or at least find some merit in each others' personal preferences, is misguided to say the least. Having a shared or common interest in the acquisition and use of fountain pens does not mean one thinks that any of the following qualities is essential, ideal, superior, or preferable: wet, broad, flex, vintage, piston-fill, transparent, shading, sheeny, and cheap.
