For me, sword is good 1v1 boss, especially to new global bosses. Aeg in the order hand is also magnificent 1shotting mobs when the vortex aura procs. The downside of aeg is that after the update, it is harder to proc. I personally used it running DM given its proc chance isnt frequent and I can still switch to my gl hotbar. Overall, it depends really on your playstyle.
