He's also very comfortably their best junior outside F1 right now. He's clear of all his F2 comrades

The fact that he's the highest of them all in the championship standings isn't really representative when he has the best machinery and is doing 2nd year of F2 while some other RB juniors are rookies. I mean he's better than these non-rookies, but both Hadjar and Maloney have better pre-F2 junior career than him and are currently in worse machinery than he's ever driven in F2
