GitHub issues, for me, is way better. You can opt-in and opt-out of notifications per thread, so you can drop out of something that turns into a total fracas.

GitHub issues, for me, is way better. You can opt-in and opt-out of notifications per thread, so you can drop out of something that turns into a total fracas. I still get email notifications for things I'm subscribed to, or when I'm mentioned. It's exceptionally handy. Subscribing to even a single mailing list tends to flood my email client with junk. Unless you go through the trouble of filtering these things, which is a total nightmare to do across multiple devices, you're just going to have to read through every single message.
