Underneath the question you can read that the 4 'everything buckets' (steemit, busy, esteem and steempeak) were ruled out.

Some of these dApps are actually very useful.
I suggest you try DLike - it allows you to take a link from any article on the internet and share it on SteemIt. Creating a post takes only 5 minutes. If you like sharing photos, try Steepshot - it's a bit like Instagram.

Some of them are really worth to at least try them out.
