Boolean Gemini is definitely under-rated, I love using it, but MIDA's impact stat is deceiving. It shows that it has the same impact as NL Shadow when the damage numbers that appear in PvP are higher on the MIDA, so that slightly higher damage WITH faster RoF, in-built high-caliber rounds, third eye perk AND increased movement speed make this gun very difficult to contend with. Like I said, Boolean is a great gun, but comparing it to MIDA is probably not the way to go.
