The mountain feat made by hulk in secret wars is hardly his best strength feat.... far from it actually. He has held tectonic plates together while relatively calm (tectonic plate = couple of trillion tons). And he has held matter and antimatter apart, that is a far, FAR greater strength feat than the mountain lifting.
Actually it would be a lot more than in the trillions, it would be more like quintillions of tons. He wasn't exactly calm though, he was pretty hyped up, but still that's a humongous feat in terms of pure strength (for example everybody got excited about All Star Superman holding up several quadrillion tons, the tectonic plate feat would put Hulk on par with A.S. Superman in terms of strength).
I wasn't talking about the feat in Planet hulk... The one I thought about was that older one, with jarella (or whatever her name was). He did it back then to, and that time he was pretty calm. But yes, that feat is insane, but still, holding matter and antimatter apart is even more insane
