Well there obviously should have been.
Anyway, yes, the Voyager crew did have a pretty good rapport but the DS9 crew undoubtedly had the best rapport. Voyager was almost always about business, fitting in a story to 43-45 minutes and that often didn't leave much time to just watch the crew in their natural habitat which was unfortunate. If we'd had a slower paced, more story-driven show we really could have seen these characters truly together and get to explore the dynamics between them. Nonetheless I enjoy watching them and am even starting to think I might like Voyager more than TNG at least with regard to the later TNG seasons.
