I don't know anything about your school, TFM.
What I like about my school is that it is a small school and I know all the pupils in the senior school and a good number of the juniors. I teach/tutor about 90 pupils. It means that I can build relationships with them. As well as teaching my subject, I take an interest in what is going on in their lives. Having a good emotional rapport is conducive to effective learning, especially with girls (I teach in a girls' only school).
Because it is a small school, I know my colleagues well and work collaboratively with them. I also have to do a lot of activities outside of my teaching duties, for example, I help out with Games. Generally mucking in makes me a good role model for the pupils in making an effective community.
I have taught in large schools and did not find my niche there. I personally find teaching difficult when you don't know your pupils well and when you know that you struggle to do the basics of your job (eg to mark books well and regularly - marking is my weakest area, btw). I also don't enjoy crowds - I hated when I was in schools of 1000+ and the sheer difficulty of moving between classes.
The trend within state schools is to go bigger and bigger, which I do not think is good. They are recognising the issues by having totally separate streams (with their own staff), but then you think why not just have different schools?
The other thing that I think my school does well is in a laid-back strictness. We have no lee-way in uniform. We specify right down to hair accessories (and they do have to have their hair tied back). The pupils just don't try it on very often, or if they do, they accept when they are caught out. The lack of wiggle room means they know when they are in the right or wrong. Parents do too. Everyone is on the same page.
We have a pretty good pastoral care system too - but a lot of this comes down to our small size. We use our Sixth Formers and Year 11s to pastor to the younger pupils, and we give the older ones lots of responsibilities within school. I know our systems are not unique to us, but I have never seen them to work so well.
I wouldn't want all schools to be like my school because my school wouldn't be a good fit for everyone. I would want there to be different cultures in different schools so that everyone can fit in somewhere. Size is not good - small is beautiful.
