Eh? I would argue that the 2010s have had the best ever drivers racing together in F1. And what’s more, because of their longevity we have seen them compete on track!
Remind me of a comparable period with drivers of the quality of Hamilton, Alonso, Vettel, Rosberg, Schumacher, Raikkonen, Verstappen and Button racing TOGETHER? It’s better than the Senna, Prost, Mansell era and better than the Clark, Hill, Stewart era.
Well I do think this is one of the strongest eras in F1 driver quality wise - if not the strongest - but it's a bit difficult to argue against the 2010's when you put Schumacher and Verstappen in the same "era".
The only year all of those (minus Verstappen) raced TOGETHER in comparable equipment was 2012, and F1 history wise, even that's hardly unique. Even 1985 had Prost, Lauda, Mansell, Rosberg, Piquet, and Senna fighting at the top. And for example 1967 had Brabham, Hulme, Rindt, Stewart, G Hill, Clark, Gurney and Surtees all in competitive cars.
