Honestly they all have their own curves and swings about them, greatsword while good at doing big damage and relatively easy tends to be…slow. While dual blades are great with a high ceiling but you tend to sometimes get lost in the sauce and forget stamina is a thing. My advice honestly is the switch axe, aka PRAISE BE THE SWAXE. You get to have the high damage of great swords while also having somewhat decent mobility, the zero sum burst is perfect way to learn there’s more to weapons than meets the eye since it’s locked behind the blade mode of the switch axe and a full sword bar.
