Which school to choose?

I am looking for admission of my sister in 9th grade (current session). She was studying in Shivoy School, govindpuram but it was so toxic , there was a lot of pressure on her to perform well being the topper of class, teachers (including sir) used the hell out of students over petty things like taking leave before unit test for preparation etc. she was literally in depression ever since she came in 9th class.

Now she is in the middle of the session and I have two options in hand that are Nehru world school and Brightland school in Govindpuram.

I am unable to decide which would better for he both environment and academic wise.

If anyone could please provide a review or share their experience with either of the schools, that would be a great help.

Thank you for your time and effort.
