There's no absolute pros and cons: features become so through people's eyes...
Of course, there are many other different features to discuss! Landscapes (if you didn't like the Meseta, you may not like the VdlP...), distances (less accommodations on the VdlP, so sometimes, long unavoidable stages), "busy"ness (
a lot less people than the CF), etc, etc.
But then, I think the main difference between the CF and the VdlP is somewhere else...
There is one thing in common with both ways: they are both Ways f Saint James and so, have that unique and mysterious quality that make of them more that just trailing paths of dust. This is what I'd call the "Camino feel", and you'll find it on either the CF or the VdlP.
However, each Way of Saint James expresses this quality in a different manner: they all have their own personalities, like living entities.
What many people call the "Camino feel", I call the personality of the CF: open, busy, loud, festive, a bit crazy, joyful, extroverted but still true, deep, intense and wise. A personality that is specific to
this Camino and that is, imo, quite an "anomaly" among all the Caminos. Nothing negative here, just observing
this Camino's personality is very unique compared to the ones of others Caminos, that have a lot more in common.
The personality of the VdlP is very different from the CF: fierce, though, austere, testing, quiet and yet proud, generous, caring, upright and whole. As a consequence, walking it is a very different experience as well: the VdlP is more confronting than the CF. While the CF "wraps up" its experience and its teaching in a joyful way, the VdlP kind of throws you to face yourself. Though love... but amazing experience!
So, no pros and cons... just 2 different potential guests to visit. Now the question is, which one appeals more to you?
Hint: ask your heart and intuition, then wait for their answer. That'll be the right one
One more thought here: somehow, somewhere... the answer's there already!
Buen Camino!
