Two different jobs, not a competition
Evergreen content (a how-to, an explainer, reference material) stays relevant and can keep earning views long after it was posted. Timely content (a reaction to current news, a trend, a seasonal moment) earns a short, often intense spike of attention and then fades. Neither is better; they do different jobs.
Evergreen content is the more reliable long-term asset
A strong evergreen piece can keep bringing in new views long after the effort to make it, in a way a timely post structurally cannot. A timely post's relevance window closes by definition once the moment passes. An account relying entirely on timely content has to keep producing new material constantly to maintain the same level of reach.
Timely content is worth it for the spike, not the longevity
The value of timely content is a real, sometimes large short-term spike in visibility while a moment is relevant. Pursue it for that spike, and accept that it fades. A reasonable mix leans on evergreen content as the steady baseline and uses timely content deliberately, for the moments where a spike is worth chasing.
