I'll add a few more:

- insanely fast search, chat history browsing and in app navigation - unlimited unencrypted cloud storage, your chats and docs always stays available - ability to send very large files - ability to host large video and voice chats - chat automation - auto translation and transcription - mini apps - open source client, with lots of customization - phone number less sign up (you can purchase a burner number from them and sign up with that, I guess it costs their crypto (ton) tho) - sending gifts
