No, I find AF intercontinental services to be of good quality. The prices, of course, help. On board service is very good. The link with KLM provides increased effective frequency and increased numbers of destinations.
Downside is anything to do with the computer systems. CDG is of variable quality and the biz lounges are not the best.
I suppose that you could get data on flight cancellations, if that is your main negative. I was once stranded by AF for a couple of days but the strikes are usually fairly well signalled in advance.
P.S. I presume you mean €3700 or was that a little joke?
