Duchesse6 - yes, EABJM has a reputation for arrogance and unpleasantness! Not surprised you didn't like it.
EaB Monceau (maternelle and primary) is the main EaB school and the best of the bunch. I only hear good things about the immersion programme but you do have to continue to manage the children's progress through French school once they are out of immersion and in normal French school as no slack is cut for them (even at EaB). EaB collège is OK academically (but dreadful, rudimentary premises and somewhat disorganised) and the lycée is definitely dodgy in all respects.
EABVH is an entirely separate establishment - the only thing the schools have in common are their shareholders. EABVH has recruited a lot of pupils by undercutting the fees at ISP, ASP etc but it won't be able to maintain that low fee structure forever and I wonder how it will fair when its prices creep up nearer those of its rivals.
I know little of ISP, but I have good feelings about ASP from everyone I have ever know who has been there (and they include friends my own age as well as the children of my contemporaries).
