You are definitely doing the correct thing by visiting schools to help you decide. In all honesty I think it is going to depend where your DD feels she would "like" to spend the next 5-7 years. Both schools have a great reputation. Both will try to bring the best out of your daughter, support her if/when she needs it and offer her a great education.
DD has just started Ribston and even though it has been a shock to the system to receive homework every day (as opposed to once a week/month at primary). spending more time travelling to school, accepted more discipline and knows detentions will
be given etc, she loves it! It will be an eye opener no matter where they go as it is so different to primary schools. We were underwhelmed with HSFG - what suits on does not suit another.
Let you DD go with her gut instinct. She qualified - be proud - so she is
capable. Tutors do not know everything
(plus some will undermine ability in order for you to pay for more tutoring
Congrats and good luck deciding.
