DAV Gopalpuram or Sankara Adyar confused help me plzz!!!

Dear friends,
My son is 3 years and 9 months old. we r transferring from bangalore to chennai soon. for the past four months, we applied in alomost 8 schools. im not against any of the below schools as i really dont know about chennai schools.

1)He got in DAV as my husband is an alumni there.
2)He has shortlisted in sankara adyar too. Interaction is on next week

* DAV reviews

So far im getting mixed reviews like
1) good school
2) brand value
3) very stirct
4) Kids will have pressure - i fear whether my kid will be able to cope up the pressure.
5) not co ed - as kids need a co existing environment for gender sensitising ryt. for this reason im hesitating to admit in DAV.

* Sankara
1) good school
2) less pressure twrds kids
3) way of handling the kids is good.

Plz tell me ur opinions. i know all schools will have negative aspects and positive aspects. if any of the moms whose kids r in the above schools plz give ur views also. so that i ll come to a conclusion as i shdnt feel guilty later.

Regards
Kavitha
