dino is a gnu+linux software, built with gtk4. If you’re using windows then the option is gajim, which in order to support omemo needs a plugin, though I can’t tell much more than that about it since I can’t even recall when was the last time I used windows.

That said, conversations has one important setting if syncing devices, which is indicating that the client won’t delete messages, the server will. Not sure why that is not the default, I guess statistically most xmpp users just make use of conversations and that’s it. The other important setting is configuring security for omemo always. Dino doesn’t need any setting for letting the server delete messages (it does when there’s no pending device to be synced) and doesn’t offer that option, and at the moment the user must be careful and set each conversation to be secured by omemo with no exceptions, but it’s already merged on master, and waiting for a new release, the option for omemo always, as on conversations.

That said, using xmpp doesn’t imply not having jami installed and keep trying it. Who knows, maybe you like it and it works fine for your purpose, and you decide for it to be you main messenger application.
