Replacing garage roof, PVC or Coroline?

[peca27]

Morning all

Have a detached 1960's garage with asbestos sheet roofing. Want to replace it with a corrugated sheet material. The cheapest stuff seems to be a clear PVC sheet:

But I'm after a sheet material that will last longer, has anybody got an opinion on the Coroline sheets?

The Coroline seems to be more expensive..............is it worth it?
