Purgation's Atrocity vs Jagras Hacker III vs Defender Great sword

[Nyxon]

I would like to know which one of these three in your opinion is the best base game great sword and does any of these games have upgrades for iceborne. I'm gonna get iceborne very soon I couldn't because of loads of other games releasing recently so I would like to know if they have upgrades for it!

Defender is pretty much always better than anything else in the base game.
They are literally there to get you through the base game fast to get into iceborne asap.

If I were to pick any of those 3, I'd go for the Nergigante one.

That being said, they all have upgrades into iceborne, except for the Defender Weapon.

Only Jagars Hacker and purgation atrocity have upgrades in iceborne.

defernder for base, jagras has upgrades you can do during iceborne but atrocity wont be able to get upgrades till end of iceborne + grinding to level up master rank.
