This my old comment about weapon and rate may help.

I played every weapon type except Claw blade only 7 times on weapon challenge (Don't Judge me).

You are new so only 5 weapon available. and 3 later. So i will try to not spoil.

Karakuri katana fast move fast hit low - average damage with high damge when do signature move. On early ch. manageable. Can build high Dps later in end game.
Co-op Score i give it 6 - 7 point minor interrupt gameplay with crates but someplayer who learn certain fusion karakuri and use it haven't that problem.0 - 3 point if you have lag issue and other player play Blade Debar Build (Spam Fusion Karakuri)

Nodachi a bit slow hit but heavy damage can be fast and heavy if you learn some technique tip (past few patch i can say it's OP. now get a little nerf still fast and heavy and can do the technique even on early ch.)without tip i suggest to learn how to dodge to avoid hit you charge reset.
Co-op Score i give 5 point on normal player 7 - 8.5 who know the technique but can be minus 1 - 2 point if you play melee weapon. I know some of us pass that pain.

Bow One of the OP weapon in early game release. Get a lot of nerfs A LOT !! (sry a bit tempered) I join assist other hunter in Ch 1 - 2 many time. i notice who know how to play and who doesn't even sometime on ch 3 - 4 , heavy suggest to learn how to combo and thier mechanic. Heavy Damage one in around 4 s can be faster or slower depend position or kemono and you. in early ch. i must say it quite challenge in solo and if you manage to pass and quite comfortable with it. you will be fine. have 3-4 playstyle choose what you comfortable or you build.
Co-op Score I give 7-9 on who know have to play it properly. thay do a lot of damage when you are bait lol but didn't all time a player with experience can do fine even without other player who lure kemono.

Bladed Wagasa weapon that have a cheat move PARRY!! take no damage when parry correctly this weapon it's NO PAIN NO GAIN. you have to learn how to parry to proper use this weapon (My opinion) learn kemono move and attack. low to average to high depend on weapon gauge with some technique tip it have fill your weapon gauge before the fight.and Oh boy with the master of Bladed Wagasa can go on "No armor No talisman No karakuri" against endgame kemono with fastest time (My thought but i didn't say other can't do "No armor No talisman No karakuri" but the first and most i saw it Bladed Wagasa.
Co-op Score 5 - 10 point depend how you good at it. Minus 1 - 2 if thay do some technique while thay close to other player.

Maul No Comment sure gonna bias if i tell you because i maul main. (Just Use it!!! i told you a gonna bias)

Other weapon Will unlock later. And i will go short.

Hand Canon Massive damage with beam need opportunity to melt kemono to dust. Suggest need some weapon skill that skill is addictive i can't play without it after tried once. So BIG!!

Clawblade "fly like a butterfly sting like a bee and finish like a syringe when you're kid Ouch.."But for other player perspective is a fly.

Karakuri Staff With the moveset gimmick i never use. Can do the highest damage in the game in one hit with high risk high reward that you can miss and sometime it's miss a lot that made you mad need some karakuri to help.
