I rate Leclerc higher than Norris on pure pace, for sure. Charles is a very very fast driver, there are no doubts. But look - at least Norris didn't bin it from the lead (although he did come close in Singapore), didn't bin it in quali, didn't spin out to lose unnecessary points. His mistakes generally have been related to the start procedure or trying to play it a bit too safe on lap 1 + some McLaren lapses in judgement. If Charles were in that McLaren this year sure, you could say he would have won more, had better starts etc, but then looking at the past few years, including when he had a very strong car in the first part of 2022, there are still those times when he perhaps pushes too hard and loses the car. Which hasn't really happened with Lando.
I think that between the likes of Leclerc, Norris, Verstappen, Russell ect there's probably not really much at all seperating them on pure pace - dependant more on their car preferences/setup.
Verstappen is the best in all areas essentially - pace, racecraft and consistency + is also largely pretty mistake free under pressure - if he has any weakness it's that he sometimes goes over the limit when defending against a quicker car but that's about it.
Leclerc is the only match for Verstappen in racecraft, particulary defensive driving - also race pace/tyre management etc, where again Leclerc is actually pretty underrated. It's in races where he often impresses more against Sainz than in qualifying. His main weakness is those silly mistakes as you say, otherwise I see him as the second best behind Max currently.
Norris in terms of pace and race management is probably every bit as good, but his racrecraft (specifically overtaking/defending) and decision making when racing is pretty poor which is why I rate him a level below Verstappen and even Leclerc currently.
Russell is hard to rate because he's on paper done an exceptionally good job against Hamilton, but how much has Hamilton regressed if any? Again, he's likely at least as fast on pure pace as the others, but seems a bit clumsy at times when racing.
