Is Marc Márquez the best MotoGP rider ever? (spoiler of this morning's race)

[DireWolfM14]

Any MotoGP fans around here?  What do you think of Marc Márquez?

I'm a VR46 fan, and likely always will be.  I really don't like Márquez' attitude or his aggressive riding style.  I think he takes too many risks with the safety of other riders.  But I can't help but think we are witnessing history in the making.  The guy is a fucking robot, only rivaled by our own LoyceV in his abilities (in their respective field.)

Unless Yamaha really switches things around next year, or Vale jumps to another factory team after the 2020 season, I don't see him claiming another championship.  Currently Vale is 2nd on the all time win list, 7 wins away from matching Agostini's career record (122 wins.)  But Valentino hasn't won a single race this year.  Is he getting too old, or an we blame Yamaha for his lack of productivity?

Consider that Márquez is fourth on the all time list, sitting at 79 wins as of this morning, and with this morning's win he clinched this year's championship with 4 races left to the season. He is 14 years younger than Rossi, and it seems like he's just getting started.  

So what do you think, is Márquez the greatest ever?
