Not sure which Camino....help ??

It might be a long way off,but I am doing some planning now whilst I have some time. I have been debating on which route to cycle ( Leon to Santiago ) or Portuguese Coastal from Porto ( Sept. 2017 ). I know that the French way has some serious hills which is deterring me somewhat and I don't know a great deal of what the Portuguese Coastal way presents when you are off the boardwalks. Bush paths might not be great for cycling and busy roads can be scary. I also spotted a post in which an individual said the ocean wind on the coast is very strong and in one's face. Hence, I am in a quandary. I am in reasonable shape for 60, but I want this experience to be enjoyable as opposed to being arduous. I have been given some feedback from an earlier post about this but I was wondering if anyone has cycled the above and could give me a few ideas, advice, or pointers.
Thank-you.
