"Just use GA4 to measure your landing page." [DEPENDS]
GA4 became the default because it's free and ubiquitous, not because it's good at the question landing pages actually ask.
The mechanism gap: GA4 is built for session-level traffic analysis with sampling, thresholding, and a four-hour data delay. For a page where you're iterating fast and care about one funnel, sampled and delayed data is poison — you make a call on numbers that shift tomorrow.
When GA4 is right: you need acquisition context (which channel, which campaign brought this user) and you already live in the Google stack.
When an event-first tool (PostHog, Amplitude, Plausible) wins: you want unsampled, real-time funnel steps and you're optimizing a single conversion path.
The nuance: don't pick one religiously. GA4 for where they came from, an event tool for what they did on the page. Asking GA4 to do both is why your numbers never reconcile.
