I also prefer physical to digital when it comes to reading, there's nothing quite like that "new book" smell, or even the smell of a well cared for old book. My partner has a 100 year old hardback from her great grandmother that she won't even let me touch, nevermind read, hah.
I've not had much experience with libraries, myself, mostly because I was never short of reading material growing up, and as an adult I tend to buy books online via ebay (99p for a 600 page paperback, yeah sure!) or newer books via amazon/goodreads.
Bookstores, though. I absolutely love bookstores. Whether it be a small second hand book shop with 6 foot high shelves, or larger bookstores with the walls absolutely covered, I can easily spend hours just browsing and flicking through. There's a three floor Waterstones in Newcastle city center that I manage to find an excuse to go into every time I'm going through, and my (third) loyalty card (get a stamp for every time you spend a tenner) is currently half filled.
