In general, I try to minimize !important use to general states only, e.g. .hidden which should override normal rules.

The difference in actual runtime performance here is so tiny, I doubt if it matters in any real-world use case (who on earth matches millions of selectors, not to mention in a loop over time?).
Just use what's more readable and makes sense in your context. If you nailed the big stuff, tweaked the medium issues and ran out of micro-optimizations, come back to this tip.
