Dianie, I have had both, as a matter of fact. I had a Sully in the last house and I decided on the Cornufe with 2 ovens in the new house. Reasons? One issue was availability in a rather short order of time. I adored my Sully. I would have carried her out on my back if I could have gotten by with it! However,I found that it put out a lot of heat in that kitchen, but the ceilings were lower than in the current house. We put in a big vent hood over there (vent a hood, but not sure of the exact model, but way enough CFM for that range). The grandbabies were constantly accidentally touching the doors and I had to be extremely careful of that. But the cooking? Fabulous...and the look? Amazing. Now, my Cornufe... I got the forest green and it's gorgeous, also. (had the ivory Sully) and although the ovens are smaller, I have a large wall oven also, and that helped make my decision. The burners are exactly the same (5 burners). Rarely did I use the cast iron summer plate (also something to add additional heat in that kitchen). The Sully would not have fit in the space for the range in this kitchen, which was the main reason I didn't throw a fit over taking it. Now, it belongs to some woman who didn't even care to use that beautiful range! I'm so sad, but I'm hopeful that one day that house will come back on the market and one of my kids can buy it! Both ranges were bought sight unseen. The doors on the Cornufe are very heavy and substantial...love that!
When we moved, I came here to get some input and got a couple of terse remarks about my choice and so I didn't ask again. But really, you can't go wrong with either on on looks....and I'm happy with both as far as the performance. I cook every single day, bake a lot, and have a huge family (there are 22 of the immediate family on Sunday nights, more on holidays). I know that some people get these only for looks and don't use them. I'm not one of them! Cost was also a consideration and the Cornufe was less, too. Of course there are several models from LaCanche that would have worked, but we were in a bit of a time crunch and this ended up being the decision. Wolf would have also been a qualifier. Sometimes I wonder if I should have chosen the Wolf, but "looks" are a big deal to me, too. I spoke with a very knowledgable man at Purcell-Murray in California and he helped answer my questions about the Cornufe. And Stan at Art Culinaire was fabulous as well back in 2005 on the LaCanche end. This forum was the place I first found LaCanche when we were undertaking a kitchen remodel then. SO many great folks here with great advice! Just do your homework, decide on the look you like best, and go for it! I don't think you'll be disappointed either way!
