For an EPQ you should conduct some proper research - put together a survey with some descriptors for brutalist architecture in general and a couple of specific examples (with pictures) and ask people to rate them/pick the descriptor words/phrases they think are most appropriate.
Asking vague questions on a forum isn't likely to get you much useful information. Especially asking in a student architecture forum where the opinions are likely to be very different to the opinions of "the public" in general.
