"I can tell you that, by *FAR*, the best highways are in France and in Catalunya"
And both of them are mostly toll-based and, at least in the Catalonian case, newer than average (I'd say it has more to do with the fact of being newer than being toll-based. My guest: A2 Zaragoza-Barcelona: toll based but older, therefore subpar. And lucky we are that most of the way is just a long straight, so not much of a problem).
I wasn't doing distinction between toll-based and not toll-based.
As per your example...
1 - You are including the part that is not in Catalunya... Barcelona - Lleida is pretty good
2 - I am talking in general, not an specific case.
PS:if you go the way of examples... get the oldest (toll-based) highway in Spain: Badalona-MatarÃ (1969) and is a very good one:-)
