Yes, I have walked many various Caminos. The Via Podiensis is beautiful and a definite favorite of mine. I don't know your fitness level, or how much interaction or camaraderie with others you are looking for, so it is difficult to advise you.
The Le Puy has a majority of French speaking walkers, so if you do not speak the language and are not coming with a friend or family member, you may feel quite isolated.
I usually suggest the
Camino Frances for a first time walker because I had appreciated all of the infrastructure, a very nice variety of landscape, and meeting pilgrims from different countries; many who were on their first pilgrimage like I was.
