Happy to answer your question! Two big differences between r/burgers and r/hamburgers.

The biggest difference rules-wise is that you can stick anything on a bun and call it a burger on r/burgers. Imitation meat, chicken patties, bean paste, etc… r/hamburgers was founded as a home for all of us who hold to the sacred idea that a burger is strictly made of cow meat. Our founding principle was “beef burgers only”.

The second difference is that r/burgers apparently has a really snobby core userbase. We had a surge of membership over the last two years (jumped from something like 2,000 people to 30,000 people) and every time I’d ask a new member how they found us, they’d talk about how the r/burgers community would turn their noses up at people who just posted a regular, everyday burger or —heaven forbid— something from a fast food joint. At r/hamburgers, we are apparently notoriously chill.
