I love my Wolf 48 with 24" center griddle. I use it all the time and wouldn't think about a grill. I have a large extended family and it really comes in handy. For our Christmas dinner, I seared 6 whole beef tenderloins on the griddle and finished in the oven. I made potatoes Lyonnais, zucchini and squash, seared scallops, all on the griddle. I could not have done it as quickly without the 24" griddle and the plus was no pans to wash. For me, 12" is too small for a griddle or grill. If I need to grill, I have a large grill on my deck. I have never needed more than the four burners if you use the griddle. It was by far the best decision I made for my kitchen.
