Ah I didn't mean here, just generally it's been said after Monaco and Baku. A friend of mine thinks the RBs are obviously faster than the Mercs, I'm not so sure. I think it's probably a combination of factors but RB having a stronger second driver coupled with Bottas' lack of pace didn't help. Can't wait to see how things play out in France; whilst I'm expecting a Mercedes return to form, I'm hopeful that Perez can deliver again.
Both Red Bull and Mercedes has different strengths, but both are equally the best cars right now. I'd inclined to believe in Lewis and Max' performances as comparison rather than comparing Bottas and Perez's (as the latter is switching to a new team too, every driver with new team seems to struggle), as both so far maintained consistent top skill level and had stayed in the team for long time.
F1 is much more car dependent, dominant cars would have the secondary driver unstoppable too, like Barrichello on 2002/2004 and Bottas on 2019/2020. It's hugely wrong to only look at the statistics and treat the secondary drivers on those cars as the 2nd best driver, ignoring or underestimating car difference. Drivers like him can be one of best in midfield, but lacks that edge to win the title, perfect second driver most of the time. Max is fighting Bottas on 2020 only because of the car difference (2nd best, but distant). Max fighting Lewis in 2020 is just a repeat from previous historic events, it shows when the years are competitive, the other elite-level drivers would be the one fighting for title with their respective top teams:
In Schumi era, when the year is competitive, it's Schumi vs Hakkinen in 1998/2000 (competitive McLaren, Ferrari step up for the first time in '98), Schumi vs Raikkonen vs Montoya in 2003 (competitive Williams and although outdated McLaren's the closest between the other teams), Schumi vs Alonso in 2006 (competitive Renault). The secondary drivers finished right behind those competing drivers (but still above other teams as their cars are the best), including Barrichello.
2001 is notable exception as Hakkinen is past his prime and the leading McLaren is Coulthard, who is another wingman in that era and thus is nowhere close to Schumi making the season Schumi domination even if Coulthard is 2nd, but neither did Barrichello (below Coulthard a bit).
And for Hamilton era, it's Hamilton vs Vettel in 2017 (competitive Ferrari) and to a lesser extent 2018 (competitive Ferrari, but Vettel is error-prone), and now in 2021, Hamilton vs Verstappen (competitive Red Bull).
