In short
Which one for whom?
GA4 fits marketing and acquisition analysis: traffic sources, campaign performance and the Google Ads integration. Mixpanel fits product analytics: what users do inside the product, cohorts and retention. Many SaaS companies use both side by side, with the same event names and user IDs in each tool.
GA4 is for
marketing teams that want to measure channel and campaign performance and work with Google Ads.
Mixpanel is for
product teams; SaaS companies that want to analyse in-product behaviour, activation and retention.

Marketing questions
For questions like "Which channel and campaign brought trial sign-ups?" or "Which landing page converts?", GA4 and its Google Ads integration are the natural choice.
Product questions
For questions like "Which feature's users are still here in month two?" or "Where do we lose people in the activation steps?", Mixpanel's user- and cohort-centred analysis fits better.
Using both
Defining event names and user IDs consistently in both tools makes it easier to read marketing and product data together; if needed, the two are combined in a data warehouse.
