Anyone who says that Pacific Rim loses to other kaiju settings based on their supposedly low weights has no idea how strong they actually are. A random drone hybrid did it first, and then Striker Berserker in the Blackout comic did it again. Jaegers really seem to hate giant doors for some reason.
I made a post here a while ago about people treating a kaiju/mecha's size and weight as their single most important attribute when it comes to powerscaling, which is not the case, else all kaiju and mecha would be much stronger than characters like Superman, Goku, Saitama, and Asura, which all weigh only around 200 pounds. No one says they're weak because they're only 200 pounds, and that's because they have much stronger feats for their size. The same is often true for kaiju/mecha.
Pacific Rim is especially prone to this. Not only are the weights inconsistent (Gipsy Danger actually has two completely different official weights for some reason) and too low for their size, few people bother to bring up their actual feats, defaulting to their supposedly low weights instead, but people in the Monsterverse community often bring up differences in weight for in-verse debates too, which matters much less than their feats.
