Valve released CS2 during peak of valorant
there itself the discussion ends, Similar to overwatch, they released overwatch 2 to keep up with valorant (and failed).
Obviously CS is better, its about 12 years old now competing with a 2 year old game. The fact that a 2 year game threatened a 10 year old game forcing them to release CS2 is already a W in valo's book.
Also, valorant is much more realistic than CSGO imo
you dont glide around irl, you are slow
you get slower while tagged instead of running
random sprays due to no consistency in making weapons. no two weapons have the same spray irl
