I used a daily-updated unstable for a while, and every so often, like once per 18 months to 2 years or so, I'd hit an early boot (grub/initramfs) bug that rendered my system unbootable. Early boot is dark magic to me, and without internet access (because my system wouldn't boot) it would take me a few hours to fix. By the time I did, someone else had filed an RC bug report which would have prevented that package from upgrading, and it was generally fixed a few hours after that. But that didn't help me fix my broken system.

That was the risk I accepted. That's what unstable is for. And you need somewhere like that to find those bugs.

But that's what you need to be able to handle if you run unstable. So I never recommend it to anyone; if anything I warn people off. If you can't make do with stable+backports, try testing. But don't try unstable unless you know enough about it to understand why you shouldn't, and still want to anyway.

Definitely don't run unstable because someone on the internet told you it was a great way to get up-to-date packages.
