Bro is the Cristiano Ronaldo of valorant, Mr. champions league. He would have bad games here and there but in big games he always turns up.
FIrstly Messi IS a better player and there have been countless times Ronaldo has not performed under pressure, he gets sung all the praises for scoring a goal in an important match while his teammates get ignored for actually creating that goal. Messi often focuses more on the creator role in big games and maybe why you think his level drops, you cant name a game where Ronaldo has not scored and still was impactful but whereas for Messi there are countless amounts of the game as such.
