Welcome to AA Fishfriendly!
I love canister filters, but have no experience with fuges. So I can't help you with the pros and cons of the fuges. Pro of canisters: Flexible, they hide easily, very quiet (if you pick the right brand), easy to maintain without spilling water (once you get used to it), and very simple to setup. Cons: More expensive in the beginning compared to a hob
. But well worth the price.
