I'm using it for years and since some time primarily with a chat mail account.
It's instant, has no spam and just working as intended. It keeps working with unreliable and really slow networks, chatmail relays have a TTL of 60 seconds, iirc.
Adding a seperate device or backing up your account is as easy as it gets. All supported platforms are treated equally.
Webxdc apps are awesome and have no internet access of themselves. For example I use a shopping list with my partner.
There is experimental videochat support if this is your cup of tea.
Right now they are working on seperating your identity from your account. This is the basis of the planned multitransport feature. Meaning your message is sent to multiple relays and if at least one arrives, your messages gets delivered.
Please don't think of email when you think of Deltachat. It uses email for transport, although its not classic email. The devs are working hard to reduce metadata and implement the features of DC within the encrypted part.
Ping me if you want to message me in DC.
