so basically majors katowice and cologne are the big dawgs of tournaments basically masters and champions
and the other S tier tournaments held by different organizers are funded by gambling sponsors and are for money and for fun
The CS circuit is organized by multiple TOs like ESL (ESL One, Pro league, IEM), PGL and BLAST.
Majors have the highest prestige because they are Valve sponsored events unlike the others. Which TO holds a major really depedns every year. There have been ESL Major, PGL Major, BLAST Major, Starladder Major, and so forth in different years.
As for IEM, there are multiple different IEMs of differing importance held every year, kind of like an IEM tour, and the top of the IEM ladder is Katowice. Cologne comes in close but historically, IEM Katowice holds the greates prestige.
Different TOs organize the yearly calendar in such way that there are minimal overlap between the big LANs,especially those by the important 4 TOs, but some of the events do overlap a bit.
