Both are ok. Neither is against Scripture. It comes down to what the person feels most comfortable with.

Focus on the Family excerpt
For our part, we don't believe that cremation needs to be viewed as a
spiritual issue. One could just as easily argue that the custom of burial in ancient Israel was nothing more than a reflection of the Bible's
cultural context. It's true, of course, as your husband suggests, that the Resurrection of the Body is one of the most important aspects of salvation in Christ (see 1 Corinthians 15:42-57). Nevertheless, the fact remains that
all physical bodies suffer disintegration, whether through decay or through fire (Genesis 3:19). The idea that God cannot resurrect them in the one case as well as in the other doesn't hold water. He does not need our specific ashes and chemical components to bring about resurrection. Why not? Because the resurrected body is a new
spiritual creation (1 Corinthians 15:44).
