Hello, i can not decide wich one to buy, the reaver karambit or the ion. I really need ya'll guys' opinion

I was mad cuz bad and then I remembered my first game. I was playing jett and thought that her smoke was a grenade. I want to hear other people's first games because it makes me laugh whenever I remember the smoke grenade.

Ive been playing Valorant for 4 days or so and got to finally play comp, I ranked Iron 3 (I main neon and killjoy), is this considered a good rank to land in in your first time?
