Dear bribby, I'm sorry I have no experience to directly compare Bertazzoni (great looking to be sure), or Thermadore to the Wolf. For what it is worth, I've had my Wolf 30" dual fuel for about four months. It is a dream machine, from the gas range top to the electric convection oven, and has exceeded all expectations. It is the most accurate oven I've ever baked in and I love all the functions, including proofing mode and broil. Everyone in the family has put on at least five pounds from the yummy baked goods and breads we are baking daily. Of course you are going to pay a lot of money for it -- but that is the only downside I can think of.
