Ghost managed hosting gets more expensive as you get more subscribers, I don’t think Patreon does. You also have to set up the payments processor yourself (usually Stripe), and if you self-host, you need to set up an email service like Mailchimp. Ghost also has much more basic community features than Patreon, and doesn’t do per-user RSS feeds, so stuff like subscriber-only podcasts are more difficult.
