Completely banter aside, he isn't for me.
Lewis, Schumi, Senna and Prost easily ahead.
For me Lauda too when looking at how he changed and dominated the sport but also just how great of a champion he was for F1.
Alonso I rate higher as a pure driver, Max probably has to edge him all time purely based on his stats alone but I think prime for prime Fernando beats him.
And thats not even counting drivers from way back when where there's certainly one or two within a shout for top 5.
