Reddit mentions of Der Herr der Ringe

Yes, Carroux is the original. Krege is (in my opinion) terribad.

I think the differences between the various editions of each translation are only cosmetics (except for the appendices/preface being in them or not) - printing style, paper, illustrations and such.

I've only ever owned one edition of LOTR (I switched to English when I was a teenager), this one. It's not in print any more; the design (it's an actual Red Book), paper and such are nice, just the illustrations are not after my taste. Someone painted cosplayers, the images are "art", but they just don't look like my mental images.

This here looks pretty, seems to be the newest incarnation of the Carroux translation, an anniversary edition with Alan Lee pictures. I suspect it's going to be the same ones that are in my English-language edition, and they're very nice.
