^^^^C'est ça^^^^Why don't you try both, listen to the results and see what you prefer. You'll also know what you're working with so where a more ambient vocal might work for one song, a totally dry one might work for another etc.
^^^^C'est ça aussi^^^^Like the above comment, you should listen with your ears. If something sounds good to you, and every engineer disagrees, who cares? It's your work and your recording. Becoming a better engineer is all about trial and error.
