I’ve been on Debian Testing maybe 15 years at this point. It’s great. Though wouldn’t recommend it if you need out of tree drivers or are starting out. If that’s still not close enough to the edge there is always Sid and Franken Debian if you want to mix and match (not recommended, but can be useful).
It’s nice to have your more-up-to-date desktop systems with the same packaging system as your Stable servers.
Arch definitely has an audience. I think it is very much for those who like to tinker and play with Linux rather than those who want stability.
I personally wouldn’t recommend Debian testing as it has way less packages and slower security updates.
