What do you think are some of the most underrated weapons that are ACTUALLY really strong?

Huge emphasis on really strong. Not a niche weapon you like using but something nobody talks about ever that is actually really powerful. Imo tektite arc is probably the most underrated. It's been in the game for ages yet NOBODY uses or talks about it but I tried using it today and wow. It's really strong? It has really really high dps for a melee weapon AND can be used at range with some effectiveness as well as just being really cool and fun
