Scoil Bhríde or Lios Na nÓg (Ranelagh)

I am in a predicament that I never in a million years thought I would never be in. My son has been offered a place in both Naoínra Bhríde and Naoínra Lios Na nÓg. I know that the Naoínra that I chose for him will obviously impact on the school that he goes to thereafter so I am desperately looking for some advice on which school would be the better choice. This is my eldest child and I don't really know parents from either school to ask for their advice. In short, my son is very outgoing and he loves getting involved in games and sports. He has some Irish but I am not concerned about that because he will learn. Anyway, any advice at all on the differences between the two schools would be much appreciated.
