Note: 1st option doesn't grants every single power, You can have multiple but not every.

Depends which power or powers it is, doesn't it? If you don't know which one power you're going to get (option two), you should probably choose option one.

Hm..option 2

Is rather have every single variation of One power

Let's not forget there is Selective Omnipotence which would be an omnipotent variation of that power.

Is this some sort of quantity vs quality type of thing?

@Qwertyuiopasdfghjklçzxcvbnm no.
