Valorant has better gun balance, there is no P90, Valorants Deagle doesnt kill you in 2 hits up close, M4A1S equivalent actually 1 taps you close range. These are only few examples.
Its a quicker game in a way, there are rare dull moments when you play it. There is also nice variety due to characters having different abilities, it doesn't get boring that quick, you can always change and play in a different style. In CS:GO you just play mirage over and over with the same nades and same smokes all the time executing the same way.
Everything is more visible in Valorant due to its graphics and characters are more upright they are not bending in half almost when switching to a different weapon.
Weapons are more accurate + the fact that you are fighting at shorter ranges enhances that. If you miss you probably missed, I do admit tho that hitreg is sometimes wack.
Scoped weapons don't blur out like AWP and their scope is not covered with some shitty dirt.
You stop immediately when pressing AD at the same time granting you accuracy.
And one thing which is really important is that Valve didn't care about CS:GO for shite, when Valorant launched they just started pumping out updates after update, piece of shite company.
