Why pick just one? There are a number of excellent Discord/Matrix bridges available which make it possible for users on both sides to seamlessly participate with users on the other services. If you want to get extra spicy, there are even bridges from Matrix to IRC, Telegram, or Slack. And they work transitively -- if you've got Matrix/IRC and Matrix/Discord bridges running, users on Discord can see and communicate with the IRC users, for example.
