English is three languages smashed together with thousand of words borrowed from dozens of other languages (Latin, “Proto-German”, Norman French). There’s no other language that has such a rich vocabulary.

To me, Finnish is the only interesting language in your list, due to not being related to the rest of the Nordic languages or Russian (Finno-Ugric). It’s also purely phonetic, which is nice, but what a shame about all those case endings. I am definitely biased as I learned Finnish as a teenager.

Might as well take this opportunity to plug Bill Bryson’s book The Mother Tongue: English and How It Got That Way, it’s a fun read.
