In the US, UCL would be almost unknown outside of academia and global prestige industries like consulting and banking, but if you’re applying for a masters, that’s academia, where they certainly know of UCL.
Search for other programs like that as well.
I’d say that UCL is a peer of UMich. Like UMich, UCL is strong in almost everything and not quite Ivy/Oxbridge level but Near-Ivy/Oxbridge. Like UMich, they send grads to the City/Street. Both take in about 5-6K first year students each year.
