GOAT is subjective but I would probably say no.
Achievements wise they are great but they don't really have the record for anything. They have 2 Olympic Golds, but Gritschuk & Platov have them consecutively (I don't credit team medals the same way). They have less world titles than a whole bunch of teams, even with a much longer career. They only won the grand prix final once which is a big mark against them historically as that is a major event. Weaver & Poje actually have more grand prix final titles than them, LOL!
And they were far from the most dominant. Even having a long losing streak to Davis & White, who are a great team themselves of course but aren't even brought up as a GOAT contender, smack in the middle of their primes. They did win the majority of their head to heads with Papadakis & Cizeron, but lost the majority of the free dances, winning most of their encounters due to odd short dance issues P&C were having. And that was V&M at their all time peak, while P&C probably have yet to reach theirs.
Most of all as all of Gritschuk & Platov, Torvill & Dean, Virtue & Moir, Klimova & Ponomarenko, Pakhamova & Gorshkov are relatively close in achievements I look at intangible impact. And in that I would say G&P are clearly last and V&M arguably 2nd last of those 5 teams. Torvill & Dean are by far #1 here, and that makes them the GOAT if I had to pick one. There is no program V&M ever did which will be as talked about as atleast 3 of T&D's- Bolero, Mack and Mabel, and Barnum. T&D in their primes were also unbeatable, V&M in their primes were not unbeatable. T&D's Olympic loss in 94 at an old age where V&M probably wouldn't even be medal contending anymore if they tried to compete that old (it is around the age V&M would be in 2022 and I don't think V&M will even medal at the 2022 Games, let alone be contending for gold, in the unlikely event should they return), was a much bigger controversy than any of V&M's losses to D&W for instance. The press were literally so irate they had to have a press conference just to explain the scoring.
