If you do a lot of cooking, and you have the room, and the ventilation ability is there, then it might be worth it.
Been in appliances for twenty years, and I have friends who are redoing their home kitchens, and are going for the Wolf free standing commercial type ranges, these can be quite expensive, but have features that some of the commercial ranges do not, for instance "duel fuel" convection oven. I have come to find that if you do any kind of baking at all, having a gas top and an electric oven work well together, not to mention it comes with a self cleaning oven. Folks order these commercial type ranges, and then realize oh sh.. I have to break out the Easy off. One advantage to the commercial oven is that you can fit commercial size full sheet pans in the oven, Wolf I believe is the only residential manufacturer to finally get that right.
The Wolf come in a 60" range, and has the duel fuel, and the "french top" and other commercial features.
The 60" has 16,000 BTU surface burners, and 500 BTU at simmer. Commercial ranges can have upwards of 28,000 BTU full open, and some do have a simmer at 7,000 BTU. It all depends on how much cooking you do, and how fast you need things to cook.
Wolf (and others, some got it right) is the home appliance manufacturers answer to the home cook who wants to have commercial ability, but did not always have the access to purchase such an item.
Just an fyi, these appliances can cost $600.00 and beyond to deliver and install.
I have included the link for Wolf, here in town Bonnycastle appliances sells Wolf, as I said these are expensive (but so are the other) you just have to weigh out what features you might like to have that the commercial appliances do not, and vice versa.

Good luck
