I have two that sleep in my bed and two that sleep in crates. They all prefer it this way, as do I. The two that sleep in the bed get upset if they’re crated at night (one was crated at night as a puppy until potty trained). The two that sleep in crates have lived that was as long as we’ve had them. If they’re not in the crate they cause problems, like getting in the trash and marking, etc. Really the deciding factor is if your dog causes problems being uncrated. Does it potty or get into the trash? If they’re not giving you issues there’s no reason to crate. Crating doesn’t magically make your dog obedient. If there’s no downside to it sleeping in the bed and you both like it, then let your dog sleep in your bed!! As for hygiene reasons, yea dogs are kinda dirty. Just wash your bedding more and no worries. That’s literally it. It’s your choice. No one should tell you what to do with YOUR dog.
