what would you do in this situation?

You need to specify how strong/weak you could be. As long as it’s not dying weak I would chose the infinite luck. Plus, if I’m so lucky there would probably be a way to cancel the weakness out. That’s a good would you rather though.

If I had infinite luck I could easily gain power/strength

Plus, strength and power against what? People trying to fight me? I could easily just shoot them with a gun I bought from winning the lottery

Ok it is proven that strength is superior.

infinite luck hell yeah... I don't have to be strong to make shots

but what if you were so weak you couldn't make those shots?

yeah but you have luck so no matter what happens you'll still make it in

true...true
