Love the guide, I refer to it a lot
I would say a Hit Hell TypeRI/RIFLE (or a hit hell laser which is much cheaper but less ata) is worth considering for some spawns where auto lock isn't wanted, it also has the longest range of the hell guns.
I've found it useful in certain spawns in episode 2 sniping gees from a big distance or aiming for certain enemies that unlock the room.
Its more of a legacy gear suggestion but Stealth Suit has an interesting property that it removes weapon equip lag so you can attack faster when changing weapons. Might not be optimal given the other options but is worth considering possibly.
