I have spent many years using French and Spanish airspace. Unfortunately the vast majority of comments on here are quite accurate. The unprofessional and blatant vectoring of non Spanish/French aircraft, ignoring English speaking a/c in favor of their mother tongue, and basic poor controlling are frequent occurrences.
The training and standardization in these countries is fundamentally flawed. All the above events happen many times an hour and their trainers and standardization personnel cannot fail to see it and still do nothing about it.
The poor quality of control in these countries is all the more apparent when you compare them to the high standards and professionalism displayed by the Dutch, Maastricht, German, Swiss and of course the UK, to name a few.
We had the Shorts 360 fatal at CDG some years ago when language played a key part and it will take another accident for something to be done about these poor standards.
