Should I start with Pandemic Legacy Season 1 or Season 0?

Across the reviewers we read, Season 1 is the most established entry point and the most reviewed, with a year-long cooperative campaign. Season 0 is a Cold War prequel that plays as a standalone campaign and is often suggested for groups that already enjoy the Pandemic system. Either works as a first legacy game; Season 1 has the broader track record in the signals here.
