Multi language domains

since domains per language can be set i have been wondering what the best practice is.

or on the other hand

which both work basically the same as in terms of seo and geo identification.

how about using translated domains instead? i assume this should be possible by language settings but is it a good idea or should this rather be avoided?


(or even with respective geo domain ending (.de, .com, fr)…
