My DC are at Maple. IME it's a great school - so long as your DC fit into a fairly small conventional box. If they "overhang" it in any way - whether that's through Special Educational Needs or being Gifted and Talent - the school doesn't know what to do with them. They want to teach to the middle.
It's a very well-equipped school - mainly thanks to a wealthy and generous parent body and the grounds are lovely. Lots of space to run around in the fresh air. Some of the teachers are excellent - but some are, frankly, crap. Disengaged and disinterested.
The former Head was very old-fashioned, and the Acting Head has wasted an opportunity to bring in a new broom and instead has stuck to his way of doing things. She's quite timid, tbh, seems to be very nervous around the parents (though not the kids).
Their recent Ofsted moved them from Outstanding to Good, but was largely very positive.
I have found the pastoral care lacking. My eldest child is on the autistic spectrum, a fact they ignored for years, insisting she "seems fine", and as a result whilst she does very well academically she's ended up completely socially isolated. My son has been repeatedly bullied by his classmates, and this is continually minimised by the school.
We've only got a couple more years ago, and moving them now would distress them, so we're going to stick it out, but given my time again I wouldn't send my DC there, I would look for a more nurturing school.
I don't know enough about City to comment, tbh. As you may or may not be aware, the catchment for Maple is really tiny, so if you don't live very close it may not be an option for you anyway.
