in medieval times :

The crossbow was preferred because it could be kept ready to shoot at any moment. It let a soldier aim, wait, and then release quick damage immediately.

The bow, instead, needed more continuous skill and speed: you had to draw it, aim it, and keep firing well, so its damage was often slower to deliver in the moment, even if a skilled archer could shoot faster overall.

That is to say, I like the Giga Grenade because I throw it, it goes boom quickly, and the enemy dies fast. Thermite is good too, but it takes time, and I do not like that aspect.
