1. World Government.

They have to be considered the greatest power in the world, as they are the only one we know of that actually spans the entire world, and controls, presumably, the majority of it. I don't think they would be audacious enough to call themselves the WORLD Government if more than half wasn't under their control.

2. Yonko ( I believe each of them deserve their own personal space here, I don't view them as a collective, simply cos they're not.)

The only group beyond the WG that actually encompass other Kingdoms or Islands within their sphere of influence. The revolutionaries do free countries, but they don't take control of or police them afterwards, presumably because of the eithics, but I think it reasonably to make the assumption that group of freedom fighters would also lack the manpower. The Yonku individually are stronger than the admirals, going by the fact that Whitebeard was constantly getting weaker throughout the entire war as his illness and old age drained him, yet he still swatted Aokiji out of the sky and beat the shit into Akainu, and their crews have near-admiral level warriors, Marco, Jozu and I would consider Vista as well, he didn't seem too bothered about going a few rounds with the world's best.

3. Revolutionary Army

I know they're an "Army" but I still view them as more an infiltration group than a military force. I consider Dragon to be on par with the Yonko, if simply because of his upbringing, Garp don't raise no weaklings... Garp don't raise no children, either! XD lol, it made me laugh, at least. The group will become very dangerous later in the story, I'm sure, I remember Ivankov saying it would be foolish for the World Government to provoke Dragon and Whitebeard at once when she thought Ace was Dragon's son, so... Still, not on par with the Yonko, in power anyway.
