I like Signal, it does almost everything I need it to do as a messenger app with the exception of handling those short videos you send each other within a family group. Be it because your children did something funny, greetings on Christmas or to show off you progress when learning the saxophone.

Yes you can prerecord and send it as an attachment, but then most of the time the video file size is too big and you need another app to make it smaller, and then it's not obvious how small it should be to still have reasonable quality to be watched on a smartphone screen. For people like my dad and my sister it's too many hoops to jump though so I'm still getting the videos on WhatsApp.
