The one in China a couple of years ago looked as big if not bigger (22 seconds in)Fuck knows. Cameras can play tricks etc. but I don't think I've ever seen a non-nuclear explosion so big.
I reckon the fuel ingredients and blast velocity will also make some explosions different to others. The Beirut and Chinese explosions certainly look different in many ways, even if the resulting fireball might have ended up being similar in size.
