Pick 3 weapons the other 3 will be use against you by another human
You have full knowledge and skill to use them. Powers stack
Stormbreaker (MCU) - You get Thors powers
Mjolnir (MCU) - You get Thors powers
Wonder Womans Sword (DCEU) - You get Wonder Womans powers
Power Gem & Reality Gem (MCU)
Ultraman - You get Vibranium armor and all his powers & can summon all the robots
Iron Mans Latest Armor (MCU) - You can summon Hulk buster (the most powerful one)
The power gem doesnt make you stronger. It just gives energy blasts.
WW speed and strength stacked with Thor's strength and durability (Stormbreaker) stacked with another set of Thor's strength, durability (with Mjolnir).
Reality gem just creates illusions right? It doesn't actually change reality does it?.
