Kage level is a bit of a poorly defined level because the kage we see have such a wide variety of levels. Hidan doesn't really fit the normal level curve because his main power (immortality) isn't really direct power, so it heavily depends on circumstance.

Still i consider Kage level to be about the lower-end spectrum rather than the higher-end. Hiruzen and Onoki are probably better described as around Sannin level, while people like Hashirama and Madara are more Biju-level (Hashirama on the 9-tails end and Madara on the 1-tails end). Then there are a bunch of Kage that seem to have no definitive level (Raikage are extremely specialized in a way that evokes Jonin-level yet can often match Jinchuriki. Tobirama is difficult to pin down. Nagato's circumstances make him a bit of a weird inbetweener).
