Hmm... if the power granter is essentially Meta Ability Creation, and I can also use it on myself, I would take that. It would be cool to grant people abilities, as well as get some myself. If I couldn't grant myself powers too, I think I would feel kind of cheated, like, "I was the first to gain a superpower! But all I can do is grant other people powers..."
If not, I would take Multiversal explorer with Meta Luck. The multiverse is infinite and interesting, and it would be cool to explore it knowing I will be safe and have everything I need due to the sheer level of luck I possess. Meta Luck alone would make me godlike, as all I have to do is want something enough and the luck means I'm probably going to get it. There's a reason it has uncontrolled Absolute Wish as an application.
