So i dont want to spread hate I honestly think that both regions are great and im kinda tired of all the toxic children. Here are some stats which hopefully will calm both sides down (probably not though).
Here are all the NA v EMEA matches in officials i could find (might have missed some)
SEN 2-0 FNC
V1 2-1 TL
FNC 2-0 V1
SEN 3-0 FNC
100T 2-1 GMB
SEN 2-1 G2
G2 2-0 SEN
100T 2-1 ACE
GMB 3-0 NV
ACE 2-0 NV
TL 2-1 SEN
FNC 2-1 C9
TL 2-0 C9
GLD 2-0 OPTC
FPX 3-1 OPTC
NA has 6 wins and EMEA has 9. We can see that at the beginning of valo NA seemed very good but EMEA definitly catched up. EMEA has 3 international wins and NA has 2 so its clear that EMEA is a better region but both are at least in the top 3 regions when it come to valorant in my opinion.
