What I will say for French banks is that in the great storm in January 2000, when destruction was massive, they very quickly put in place a system whereby customers could get a loan (several thousand pounds worth) without discussion to try to get things sorted quickly - new roofs, replacing milking sheds, removing fallen trees etc., and then, when things were settled, go back and discuss the terms. And at very low interest rates. I thought that was good.
The other difference is that French banks are very regional (ours is Crédit Agricole Normand) and may well have no connections with any other banks, which leads to difficulties and idiosyncracies.
