Front left. Tbh this is one of those things I'm kinda surprised I have a definitive answer for. I would use others if I had to, but thinking back on it I have gravitated to front left whenever available for decades.

I use the front right burner which is a medium ring. Bit if I'm using a frying pan then its the ring on the left as it's larger.

the netburst

front right

The biggest.

There's four burners, two large, two small, I think the large ones are diagonal to each other, I like to use the front right one, which is a large one.

front right unless it's something slow cooked like a stew or marinara sauce, then it's back right

Whichever one the dice land on.

front left - back left is always uncovered bc the oven vents out from that one. NEVER USE THE RIGHT ONES. idk why I just don't.
