Anfield or American Int School

My son accept by Anfield and American Internation School for K1 course next year. I would like him study in international school later as well (may be ESF). May I know which school is the good choose. I have read those message for AIS is not so good but I have seen their kindergarden which is not so bad. I have visit Anfield as well but they seem a little bit old. But their teacher said that all of their student in this year have pass the ESF admination exam. I would like to know if anyone know about it
