He is rated far higher outside of France than inside of it at least that's what it seems to me.
In France you won't ever hear of anyone comparing him to Neymar or putting him on a similar level.
He's still a terrific player, best off the ball attacker in the world to me, the pace and the movement as well as the ability to time his runs make him a threat at all time and guarantee him several chances per game.
However I don't think that he is the most dangerous player with the ball at his feet, still very competent of course but he's not deserving of these R9 comparisons, his first touch,dribbling and close control are nowhere near R9's.
I totally concur with what you say. I might add IMHO that he's more about pace than movement/intelligence (even tough the movement part is still there but less) since he's in PSG.
I remember his season at Monaco, he seemed to me more intelligent with his off ball movement and runs (tools and ability are still there).
Always felt like being around Neymar and being a 180 millions signing he started wanting to shine more rather than being just absolutely lethal/clinical.
Also as you said, the R9 comparisons always have been laughable. He's not technically not at the level of Benzema (which is probably the best among elite strikers but still not Messi/R9), and will probably never will be.
I think if he exploits his potential, he can be a prime Eto'o. Quick smart pass in small areas, no non sense approach around the box, intelligent runs and an appetite for goal, capable of scoring all types of goal.
For a young player praised for his maturity (IMHO more a public persona stuff because he got a diploma and isn't dumb as rock his football peers of his age), if anything to me his game screams to me he misses experience and "maturity". And that's normal he's only 21.
