I have to support jmnav's opinion in this,
I have found almost no other pen that has a steel nib that in terms of comfort in writing is close to its gold nib version.
My opinion is obviously partial (I have not tried all the pens in the world...) and subjective,
but yes, the steel nibs of the Pelikan M200 are springy, and I have only one other steel nib that compares (and is actually better) and that is a steel nib in a vintage Osmia. Possibly some CN (steel) Pelikan nibs from the 100N may be similar, but I don't own a CN nibbed 100N.
in my experience M200 nibs are almost always similar to each other in springiness (I own approx 10 M200s...), meaning that the steel nib in my M200s, whether pre 1997 (pen with derby cap), or modern, have a very similar if not identical feel.
Even steel nibs on my Pelikan 120s behave very similarly, and the 120 date back in the 50s-60s.
Viceversa the feel of Pelikan gold nibs from vintage to modern can differ greatly! (ask Bo Bo here...)
let me clarify however
the M200 nib is essentially springy, does not flex, but feels somewhat soft (but not mushy in my opinion)
the m250 and M400 from vintage pens is flexy (semi-flex as Bo Bo calls it), it flexes slightly and springs back fast
the M400 modern nibs are usually stiff!
so if you compare a modern M400 nib with an M200 nib, if you appreciate springiness, you might like the M200 better!
some people hate the M200 nibs, as they don't like the springiness (as opposed to true flex usually, or even as opposed to a stiff nib)...and that might be you
but then variety is the spice of life
PS oh, and yes, the assumption is that springiness is better because writing is more comfortable, in my subjective case
