Top Best School options for NRIs returning to CBE - RUH ?! Manchester ?!

Hello Dears, We are in our 40s, new to Coimbatore.... NRIs after being abroad for over 15 years in multiple countries, returning back to India and decided settling in Coimbatore. Looking for the right school community for my 10 year old twin boys. Seeking suggestions - Where do coimbatore's top cream of the cream sophisticated kids go? Fees isn't an issue... RUH & Manchester are our shortlists. Anything else worthwhile to add to the list for campus visit.
