They are the best and the only grills that should truly be called "Genesis". They are especially versatile (far more than their counterparts). Indirect is easy. I.E. last night I wanted to spin a chicken but honestly ran out of time because I forgot to pull one from the freezer. So I bought a pair of organic birds at Costco. Instead I did a simple spatchcock. Prepped the bird and "vented" the skin for fat rendering. Gave it a nice shower of a rub and olive oil. Got my Genesis hot, than stabilized it at 400 on the hood thermo. With front and rear burners on middle off. I got a beautifully cooked bird, crispy skin, tender and juicy. And some pieces I removed prior to cooking for the soup pot. But the next bird will definitely go on the spit. Something only a sidewinder can truly do well. The grills with front controls can only "pretend"
You get food cooked primarily on the "ends". So ends over done to get the middle done. Meh. With that nice wall of heat across the front and back of the grill you get perfect results
