Daisy tends to shove the entire spout in her mouth as shes drinking, it might just be some weird thing they do? I'm not too sure! That I know of bottles are just the overall safer bet, I've never heard of hamsters choking on water but then again I guess it could happen!
Here's a photo of her drinking:
EDIT: I just reread your post - I somehow read spout instead of in the hole. Oh dear. Maybe a bowl would be best..
