I don't know anything about dcs. All I know about Wolf is that it is a generally respectable range top with an oven that is susceptible to having the blue enamel chip.

And Viking is a brand to be avoided in each and every category. This is a company in free-fall that has produced poor products at a high price for many years now.

You may want to look at Bluestar ranges. They are solidly build, high performing, easy to maintain (not saying maintenance free.)

Viking has had problems for sure but that’s perhaps a little harsh.

DCS is Fischer-Paykel. They make a solid product.

Are all of these products serviced in your area? If not, strike off your list.

Since FIsher Paykel is Haier, it fllows DCS is Haier too, as is GE.

I had a neighbor who had all Fisher Paykel appliances due to ADA needs. By the end of 10 years, the drawer dishwasher, top load dryer and washer and range oven weren’t working. I had zero repairs on my Bosch appliances in contrast. I was told to stay away from Viking and the high-end showrooms aren’t showcasing Viking, which is telling. I just ordered some Wolf parts and they’re extremely reasonable when compared to the cost of other mfg’s spare parts - and they arrived the next day, even the custom order trim piece. I really can’t say enough nice things about Wolf’s customer service. Of those 3, I’d pick Wolf all day, every day.

Bluestar, Miele, Bosch, Wolf/Subzero, ... all of these have a great reputation and if there is a service network in your area you'll probably be happy with them.

If you are willing to explore some of the niche players, there are several of those for at least some product categories; and it can pay off to buy these brands, if you have specific requirements. You'll get names such as Perlick, True, Capital, Modern-Aire, ...

Lots of the other brands though, might have good brand name recognition, but their product offering is decidedly more hit and miss. If you do a lot of research, you might find the diamond in the rough among these products.

And of course, even if you stick with the top-of-the-line brands, you can find a lemon (c.f. Wolf's problem with chipping oven interiors). But as a very rough first approximation, you probably will be extremely happy with the offerings from either of these companies.

Of course, as frequently in life, you get what you pay for. None of these brands are known for being cheap bargains.

If you shop you can get some excellent bargains. I agree with M, there are lesser known brands that deliver excellent products. I got a Bertazzoni 30” double oven for 2k and couldn’t be more pleased with it. It performs and I’m super extra picky. I’d put it up against a 9k oven anytime. And I can afford 4 of them for the price of the Wolf or Miele. The best advice is to know your needs and must haves in an appliance and shop accordingly. I’m very happy I did, was able to reduce my appliance budget and get everything on the list checked off. Then there are people who don’t cook and just need the flashy logos. That’s ok too. As is needing everything to match perfectly. Most of us need some combination of all 3.

If you go by the people that post here with Wolf, it is more than just a random issue with the blue enamel. The issue has gone on since 08 and many that have posted here have had 2 or 3 oven linings go bad. They will service it under the 2 year warranty but after that it becomes a profit center for them. You must use their repair service. They won't tell you how much it costs, but starts at $800 for labor and will only guarantee it for a year. Some people were told to upgrade their ovens at their own expense and these have gone bad too. Even the new M that is supposed to fix the issue is affected. All is documented on this forum.

I generally think that Wolf is fine. It wouldn't be my top choice personally. But there is nothing horribly wrong with picking that brand. And their Subzero brand is well-regarded too.

But @wekick is absolutely correct. Don't buy any of their ovens. That's the one thing they seem to have ongoing problems with.

But if you hypothetically really loved their range top and you wanted to combine it with a Miele wall oven or maybe even a Miele combination steam oven, then more power to you. That's a nice combination.

And I think you can recognize a pattern here. This forum generally recommends that you mix-and-match brands. They all have their own relative strengths and weaknesses, and those can differ from one product category to the next.
