I was given a MINI BGE as a gift. I cooked on it for a week and ordered the XL. I have since add the MEd to the fold. The fact that you can maintain any temp you want is by far the best feature. No more refilling the water pan. No refilling the firebox. Just load it full of lump and let it go. When you are finished cooking just snff out the fire by closing the vents, and you can reuse the lump left over. I've cooked butts for 24 hours and still had enough lump left in to put a serious sear on some rib-eyes. Shut it down again, and cooked burgers at 400 dome temp.
You can bake in it. Which I love to do. Friday night is usually pizza night and the egg hasn't failed me yet. It's like cooking in a pizza oven.
I've cooked on kettles, offsets, UDS, WSM and gassers. Nothing beats a ceramic cooker IMO. I gave all my other grills/smokers to family members, and they still come to me for Q.
I wonder if picts work the same here as they do on the Egghead forum. Let's see.
I tried to post photos showing what the EGG does better than a kettle. Although some of these can be done equally well on a Weber. I still like the photos. I know they aren't Tropical Delight quality, but I'm still learning.
