I am a fairly new player to the game, so I want to know what are the best agents that people are playing now or like the meta agents. I can play any play style.

I want to become a Viper main and I just want to know which one is better for her, the Vandal or the Phantom. I like the Vandal more but it can't do anything short range. Which one do you use or which one do you think is the best? Thanks!!
