Im guessing you are from Valorant, so to quantify in those terms is difficult, but:

Majors = Champs

Cologne and Katowice = Masters 2 (the bigger one with more prize pool and teams)

Other IEM events like IEM Melbourne (3rd biggest crowd in IEM history) = Masters 1 (smaller with less teams but still important for the grand slam in ESL and for qualifying to Majors).

All else = Important and have decent prize money but not to the same degree as aforementioned, maybe same level as LockIN?.
