Mine like to put their feet in their bowls when it's hot and they also like to dig in them (making the bottom level of their cages a watery mess- but they drink more and have more fun. So bowls for mine! But I always make sure they know how to drink from bottles. For travel and such.
I would suggest offering both if you have multiple bunnies just so they have the option, why not. You seem to be building quite a big space so there would be room. Personally I have never even thought of a bowl. My other 2 bunnies in the past had bottles and my current bunny has one. I think k maybe my past bunnies would've liked bowl, they weren't messy or anything. Very calm bunnies so it would work out. My current bun is just so rambunctious and likes knocking over everything so bottle is good. I refill it everyday because she seems to drink more if I do, even if it isn't empty yet. Also I have a glass bottle with metal end, she had a plastic one and literally ripped it apart to the point of being unfixable! Lol but she hasn't destroyed this one and it comes with a spring that clips onto the top and bars of cage and one the clips onto the bottom and bars of cage so she can't tip it off as much either.
I make sure mine are comfortable using both (I prefer bowls for my buns normally) but I like them knowing how to use a bottle, in case we need to travel or spend a night at someone else's house in a kennel (I never actually plan on this happening but sometimes things happen).
