Product review (4 stars): If you must have a commercial style range, this is one of your best options.
I'll update this if we have any issues, but we've been in our new home for 2 months and so far this range is working perfectly.

We've baked cakes, cupcakes, brownies, lasagna, and mac and cheese. Nothing super technical, but they all came out great and it's nice having the space for 2 cakes side by side. The roller racks are also nice. The broiler is very fast, so watch closely. It starts up quickly.

I'm used to baking with a gas oven, and prefer the simplicity and reliability of the all gas design to the dual fuel.  We have an electric wall over, but I prefer to use this one.

On the stove part, the extra low / intermittent burners are nice, but even when they're off for most of the cycle time, they're still pretty hot. They're big burners, so they don't work well with my little bialetti moka espresso pot (4" diameter).  I put a cast iron trivet down off to the side and use it over just one point of the star, but it's really wasteful.  So while the star burners distribute heat evenly, their larger size does have a downside.

I read the other reviews, and one noted the range is noisy.  Ours is very quiet and doesn't get as hot on the sides as my sister's Blue something commercial range. We got the 366G, not the 366GH.  No vertical back on ours.  Another reviewer was claiming that Bosch/Thermador won't stand by their product, but they say they purchased the range "about 2 years ago".  It's got a 2 year warranty, so I don't know why they don't specify if it was under warranty. That same person put the identical review up for a completely different range, so I didn't give it a lot of credence.

My brother and sister in law have the monster wide version and love it. I think this style of range is a bit silly, but they make a nice focal point for a large or fancy kitchen. Based on everything I read, what the appliance store guys we bought it from said, and what the repair guys said when they came out to fix the broken Dacor range at a beach house we rented, Thermador's gas ranges work better and tend to be more reliable than most of the other comparable options. The GE line was another option we considered. If you don't "need" this style of range though, the top of the line normal looking versions with slightly less heat output are generally less money and more reliable than these commercial style ranges across every brand.

18-January-2017 update.  We're still using it almost daily with no reliability issues.  We did note one design issue.  If you leave the stove door open when broiling, the control knobs get hot enough to burn yourself on after a few minutes.  I don't know if that's a design flaw or not, but they cool off very quickly when you close the door, and they don't melt, or haven't yet :)
