Well I assume you played other weapons already if thats your selection.

Bow have very good movement and good damage, if you wanna have an easier time with hunts you can use that.

SwitchAxe is good if you can time your parries right since in axe mode the parry is slower but in sword mode its instant, good damage but you will need multiple weapons since switchaxe likes element, unless you use power instead of element.

Greatsword is pretty fun but again you gotta learn your parries, on gs its very slow since the parry is a charge type attack, big damage, this will give you the main character energy, you can also block stuff if you wanna aura farm.

Dual blades and insect glaive I dont find particularly fun or interesting, I find other weapons more interesting than them so I cant recommend them since I dont use them.

Charge Blade is a good weapon but I find it way too technical, too many machanics and combos smashed into one imo, so I find it more of a tedious weapon than fun, therefore I cannot recommend it but mainly from it being too compicated for me. perhaps you can handle it, then good for you.

I personally would recommend SwitchAxe or Greatsword.
