Ok, bit the bullet....ordered a Wolf Range, additional oven and microwave! I'm so excited.
Here's what I learned:
Wolf has the electronic features on the ovens....delay start, timed baking etc. and Viking did not. Wolf has a thermometer display that tells you digitally what the temp of the oven is and lets you know when your oven is at the preheat temp....Viking has neither. Viking has no electronics other than the ignitors.
Wolf has the dual convection system (two fans)...Viking has one.
Viking has a whole bunch of color options....Wolf does not.
Viking burners frequently go off when on the low simmer mode; Wolf simmers lower than Viking;
Wolf will be changing their burner design next year.
Wolf had continuous grates covering 2 burners....Viking had individual grates;
Wolf has a low backsplash (I'm sure that's not the right term) whereas if you don't want to have a high piece of stainless behind your range....Viking's smaller one is an additional option and costs extra....Wolf comes that way.
Wolf has better customer service;
Viking is prettier....if you want a showpiece, buy a Viking...if you want to really cook and have the range be a workhorse...buy a Wolf.
Looking at all the high end kitchen design magazines, I see mostly Wolf ranges....just an observation....didn't factor into my decision.
Rumor has it that the company that makes the hoods for Wolf has gotten wind that Wolf will begin manufacturing them in house and there's been some delivery / quality control issues on the hoods.
Door design is sturdier on Wolf than Viking; Viking has a history of problems with their doors. Wolf is guaranteed to hold 70 lbs;
I'm sure there's more but that's what I remember off the top of my head.
