I like the Defiler (Fire Axe + Sledge Hammer). The ingredients are easy to find, it gives good PP, it has a fast jump attack, it's super strong, and the alt attack is a fast sweep good for crowd control (just don't hold down the button long enough for it to become the hammer spin.) The only problem is the regular attack is slow but it isn't as vulnerable to grabs as some other weapons are.
The light sword is too slow for all it's combos, durability is low, and you're vulnerable to grabs between every swing. The Tenderizer gloves are too weak; go with the Knife Gloves instead. Boomstick is just a waste of ammo; I prefer the rocket launcher. A lot of those other listed weapons are just too much of a pain to collect the ingredients to make them practical.
