Trying to compare Leclerc/Norris:
Leclerc
Outperformed by Sainz: AUS, JAP, AUT, GBR, MXC, LVG (6 races)
P11 in AUT, P14 in GBR, DNF in CAN (reliability).
Otherwise finished top 5 in ever race. 12 podiums (3 wins)
Norris
Outperformed by Piastri: SAU, MON, BEL, ITA, AZE (5 races) - (some arguable ones)
DNF in AUT, P10 in QAT.
Otherwise finshed top 6 in every race (one P8 in SAU). 12 podiums (3 wins)
Ferrari were better in Bahrain/Saudi - probably in Australia/Japan but this was closer. Then in China onwards McLaren were better on most weekends. Only really the USA/LVG race, Ferrari had clearly better race pace. Some were close.
I also personally rate Sainz ahead of Piastri at present.
I'd argue based on this, Leclerc has had a better season than Norris.
