I prefer twitter
On Facebook your reach is very limited. If you have 253 friends then they’re pretty much the only people who will see your post if they’re online at that time. Yes they can share it, but it’s not as common practice on Facebook.
On Twitter though you can have a very limited number of followers and still reach a large audience. A simple retweet from someone with a lot more followers can really make a difference. On Twitter it’s far more common and more natural to share, and chat to the sharer too.
