In terms of adaption the film has the definitive cast and production design. A bit weird, but it caught the atmosphere of the book quite well to my mind.

OTOH, the TV series had a longer running time and was able to be more faithful to the book and fit more moments from the book in. But it looked pretty ridiculous on occasion (such as the complete absence of any scenes filmed in the desert and the use of painted backdrops instead).

And with our current remake-crazy culture, apparently there's yet another movie version of Dune in the works.
