Debian has been doing a stable release every two years since 14 years now. If you want the equivalent of a non-LTS Ubuntu release, you should use Debian Testing (besides the naming, it's pretty stable)
Yup, and Debian recently started committing to 5-year support cycles, so it's basically the same as Ubuntu LTS releases (can skip one, but not two releases), with the difference that Debian is released when it's ready, whereas Ubuntu is released on a schedule.
Personally, I don't trust Ubuntu LTS releases until they get their first point release, and even then I'm skeptical since they're a bit more loose with package versions on stable. I do trust Debian when it first releases because they're far more rigorous in their testing, though I usually wait a week or two before doing a release upgrade just in case.
I used to really like Debian testing, but I've since moved to OpenSUSE because they have a real rolling release (for my desktop) and a solid release based version (for servers). I like Debian, but testing gets a bit sketchy around release time (frozen, and then a ton of updates), and I honestly don't trust Sid aside from pulling in the odd package. I don't trust Ubuntu at all, since it has caused me far too many problems in the past.
