How many burners do I actually need?

Specialist subreddits consistently say two burners suit one or two people and small patios, three burners is the sweet spot for most households (enough room for two-zone cooking), and four-plus burners make indirect cooking and large gatherings far easier. Reviewers note four-burner models do two-zone grilling 'far better' than three because you keep more usable space when one side is off.
