I played both and if we going by the game itself I would say this, a lot of the things in valorant are spoon fed. Where it be the enemies economy or their ult it's all given to you. In csgo you have to figure out how much they have same with overwatch, players have to know and figure out if enemy team has ults.
That's why valorant is very friendly to new players. It's easy to transfer your skills if you mainly played csgo or overwatch just need to learn a few things then you're good to go. It's also a breath of fresh air to be honest, combining that csgo gameplay with overwatch character powers and ults.
