Hola
It all depends on the season you are walking it.
Iv walked several Caminos and when I walked the Norte it was in March and April - 12 years ago - and there were not many people walking it, which was good for me.
The distance between Albergues and towns felt further apart than Frances or Portoguese, and ther ewas a lot of road walking.
But the ocean is fantastic and a lot of small willage and towns to enjoy - small boat rides - in all a different experience than Frances.
I took the Primitivo when I got to the fork and it was a very nice experience.
More people than Norte, but much less than Frances.
Dont take the Camino Madrid if you want to see other pilgrims - its a walk in solitude when I walked it in July 8 years ago.
I hope this helps a little, although I cant really give you any adivce.
Maybe think about changing the season you walk in to experience it in a new way.
Buen Camino
