Id say valve cares more since csgo is a higher quality game, way more polished, there is nothing to fix really. 32 tick csgo played on LTE with 150ms is more enjoyable than playing valorant at 100 ms 128 tick. But an awp removal and a big ban wave of pros cheating and fixing in tier2/3 would be great.
I also think that the matchmaking in csgo is based, i personally finished csgo walkthrough using shotguns and pistols only multiple times - it has no forced 50% wr.
The last nail in the coffin for pooporant is the fact that it has no replay viewer 5 years after its release. Valve has 3 ppl working on csgo and it had more frequent and better updates than Valorant.
Final verdict: overwatch1>nier automata>fortnite>csgo>>valorant.
