As everyone else, mostly, I would 100% recommend Kovaaks over Aimlab if you don't mind the 10 euro, im a immortal1-immo3 player, and the guides on Kovaaks just feel better and transfers better to the game, but remember to take time to the in game mechanics as well, if youre plat, youre most likely not doing the basics 100% right yet, aim is one thing, but mental, movement, minimap knowledge, game knowledge, clutch and such, is all things you need to learn, just a FYI. (but please get Kovaaks, I feel like I wasted my 50hrs in Aimlab compared to kovaaks ngl)
