Ease of use? Are you serious? Both are easy to use. If yourr talking about ease of use to casual players then i would agree that girebolt is easier. But in the world of casuals, hitting people with grenades is cake because they make constant bad plays, repeat things that get them killed and rage rush all the time. In the world of top tier players both will be just as effective as eachother.. Eitherway you cant call something op due to HOW its used, that would be ignorant.
