There is no debate that a Lebron of Valorant does not exist right now. There is no one that is close to the metric of Lebron in both achievement, skill set variety, and/or longevity. For reference, Faker is the Lebron of LoL. That is how high that title is. Valorant is too young for us to call anyone Faker or Lebron.
However, if an alien entity decides to descend to Earth on the 19th of March and hold a meteor at point to Earth and force us to answer who the GOAT of Valorant is, we need to be prepared.
In terms of achievement, the player with the most finals trophies would be:
No one. 2021 Acend, 2022 LOUD, 2023 Evil Geniuses, and 2024 EDward Gaming have no repeating players.
However, if we were to use the 10 highest ACS players on each Champions playoffs, including longevity, and weed out the players who are not in the top 10 more than once, we would have:
aspas: 3 (2022, 23, 24), won 2022 Finals
BuZz: 3 (2022, 23, 24)
Derke: 3 (2021, 22, 24)
Chronicle: 2 (2021, 24)
Less: 2 (2022, 23)
In terms of individual value/performance + longevity, aspas is the #1 player in Valorant. BuZz and Derke is tied for #2. Chronicle and Less is tied for #3.
If we were to average out their ACS from the years they were the top 10 highest ACS in finals play offs, the ranking would look more like:
#1: Derke avg. 265.70 ACS (3)
#2: aspas avg. 225.40 ACS (3) (Won 2022 Finals)
#3: BuZz avg. 225.13 ACS (3)
#4: Chronicle avg. 236.35 ACS (2)
#5: Less avg. 222.35 ACS (2)
In that ranking, Derke would be the #1 highest performing player with longevity by far.
I understand ACS is flawed and biased towards duelists so maybe the correct term would actually be the Best Shooter or Steph Curry of Valorant... but it does not sound nearly as good as The Lebron or The Faker of Valorant.
In conclusion, when the alien entity on the 19th of March asks us who the Lebron/Faker of Valorant is, our closest player (not really) would be:
Derke and aspas
