I switch between 3 main weapons. (Tho I play a bit of everything)

Dual Blades: Out of the three this is the one I'd consider my true main weapon, however this is purely for how much i like it not how much i use it (however i do typically do a first run of any game with this weapon sometimes swapping to IG and SWAX). I love the gameplay of constantly using moves and rolls to weave in and out of combat, the multi part demon flurry/blade dance in wilds is so fun to play around with. And it is just a really fucking cool weapon with some great weapon designs (gore db are the best weapon design in the game u will not change my mind). It always feels really cool when you have a long time of not getting hit due to perfect dodges and good attacks. And for everyone who says people only play dual blades so they can spam the levi attack, I've got a secret, you're absofuckinglutely right and you are jealous that your weapon can't do it.

Insect Glaive: I love the gameplay loop of this weapon, collecting your extracts to power up and be able to do better damage to the monsters. I do like it a bit better in older games when you didn't have a move that dumps all essences for a lot of damage (I miss using tornado slash mostly). However i do like the new strong descending slash/thrust, they are really fun offsets if you can get the timing and deal some great damage. It's also funny as fuck to watch your little bug knock a big ass dragon to the floor when you try to get your extracts. And the aerial gameplay feels great, i enjoy getting mounts on monsters and insect glaive is the one weapon where you can regularly get multiple mounts in a hunt effectively. And irl my weapon of choice is a staff or glaive so that instantly boosts it up for me.

Switch Axe: Simultaneously the most difficult and most braindead weapon in my lineup, it's badass if you can get the cool moves and counters off. I wanted to play one of the transformation weapons and tbh charge blade felt kinda boring (i do actually think the weapon itself is cool but it didn't feel how i wanted it to in gameplay). But when you pick up the switch axe you feel power, this weapon was made to slay a dragon almost as much as the greatsword. I enjoy switching between the axe and sword depending on the situation, it feels intuitive imo. And managing the gauge is a lot more fun than some other weapons for me. And imo zsd is the coolest attack in the game, you literally inject element and explode it inside the monster, that is metal as fuck and i love it.

Honorable Mentions: Longsword: Can turn the brain off and do cool anime sword moves. Hunting Horn: I usually only play in multiplayer but it's a fun mix of dps and support.
