The best weapons in HoW are the snipers imo.
Her Benevolence and Shadow of Veils are amazing.
From the Vendors... Exodus Plan comes to mind. Nothing alse that stands out.
From Trials you're good with all of them, but they have PVP focused perks.
HoW has some great stuff.
Matador 64 and Part Crasher +1 are probably the best shotguns available.
Her Benevolence and Shadow of Veils might be the best 3v3 snipers, edging out LDR and Longbow with higher Aim Assist
Low Grade Humility and Eye of Sol are extremely good 6v6 snipers
Hopscotch Pilgrim, Spare Change and The Messenger are top tier Pulse Rifles
Ash Factory can be rolled into the very best legendary RL (tied with the IB one to be fair)
The BTRD or whatever is the best legendary machine gun you can get your hands on
The three exotic weapons we got are easily better than the sad TDB Exotics (Dragon's Breath, No Land Beyond, Necrochasm and PS exclusive 4th Horseman)
PoE weapons underwhelmed a little, but random Crucible/Vanguard drops, Queen's Wrath and Trials of Osiris all brought amazing stuff to the table.
