I, too, tried a PSP version of Monster Hunter and hated it (looking back, it's partially my fault for choosing the Hunting Horn which is NOT beginner friendly lol). I heard MH World was easier for newcomers, and bought it feeling a little reluctant — I ended up logging over 1000 hours including Iceborne, and then also getting the 4U haha.
Greatsword and Insect Glaive are my main weapons. I love the heaviness of the GS, being able to tackle through most attacks & the lightness of IG, and being able to jump/fly my way out of harm's way. Both of them are so satisfying to play. I tried learning the Switch Axe and the Longsword, but they never stuck with me.
I thought Rise okay, didn't play too long on it or felt the want to explore the map as I did with World or 4U. I'll still probably get Sunbreak since it's still a fun game.
