I won't even try to do an all time list. I honestly wouldn't know where to start. I mean, would Fangio, if there could be some objective way to compare, have something extra compared to the 2015 field (he was real old when he was winning titles), or would it be like someone said in 2002, that "at [his] best, he would be about as good as Pedro de la Rosa non (2002) - since in every other endeavour, records are continually broken and improved upon, and drivers prepare so much more these days.

When I try to judge drivers, I admit team-mate comparisons form a very big part of it. I know they can't be perfect (Barrichello/Irvine 1995, then both compared to Schumacher wouldn't add up), or the Frentzen-Hill-Villeneuve triangle. But those two examples obviously had factors like drivers well off form, that was clear to see.

And how do you know two drivers aren't flattering a car or being flattered by a car? Well there can be a general feeling in the paddock, and people whoa re experienced and discerning. Frentzen in 1999 and Ricciardo in 2014 made few mistakes, raced very well and were very consistent. I doubt they would be these things if they weren't performing at a high level.

But really, I will just agree it's subjective at the end of the day, and we can just do the best we can.
