SSS, I think there are teachers and schools you wouldn't like anywhere. There is also a huge difference in atmosphere between individual schools, which is only partly down to the nature of the catchment area, and is very significantly influenced by the head's vision -- some are formal, wiht uniform and teachers called Sir and Miss X, others are first name terms and anything goes re clothes. Some do project work and lots of arts-based stuff, others are more academic and sporty. You really have to go and look at individual school to see whether you like the atmosphere and ethos.
BUT I think the UK has a much wider concept of what schools should be doing than Germany does, and consequently they will have a range of policies on eg. bullying, racism, supporting lower achievers/SN and will be much more likely to have systems in place to encourage children to eg. consider the feelings of others, share, make sure people are not excluded etc. Not to say that all schools are perfect at this, but it would be hard for any school to argue that this was not part of its remit.
I also think the policy of keeping year groups together strictly by age affects the way that schools operate. It means that the concept of 'failing to achieve the class targets' doesn't exist, and the teaching is much more based on where the children are starting from rather than some notional Klassenziel. There are downsides to this dd1 was in a Y3 class (7-8yo) where a little group of her mates were reading Lord of the Rings and having opinions on the Iliad while a large group at the other end couldn't read at all. The other downside can be inflexibility I have a friend with twins who were August-born three months premature, who have really struggled at school, and she has been unable to convince the LA to put them back into the yeargroup that they would have been with according to their due date.
But I think overall the UK system leads to a more humane and child-centred teaching concept, and one which focusses more on the all-round development of the child, rather being a means of transmitting XYZ body of knowledge and washing its hands of anything beyond that.
