It hits the same number of things, type wise.
And all the things listed are terrible choices to stay in against since you cannot land a ohko and can die pretty easily, except maybe Diancie, would need to see calcs.
I mean, out of all the things you would run EQ to actually hit, when would BB not effectively do the same thing? There are plenty of enemies where fighting is a better coverage choice than ground, and the damage is so close that it comes down to having something that will take out a check. Heatran is a bitch with Air Balloon and very rarely do I encounter one without that particular item for EQ protection.
The super effective hits on Normal, Ice, and Dark types imo is better than the coverage on Poison, Fire, and Electric types, considering there are more of the former in OU that CharX wants outs to than the latter.
