Nio and L'Humaniste are amazing, and not redundant at all.
Before you jump on Nio, I'd consider trying Bergamote 22. It's also a very nice citrus. I personally prefer Bergamote 22, but I love Nio.
I like 1861 too, but it's not in the same ballpark as the above 3 are for me. I don't think you can go wrong with any of the above 3 honestly.
