JLGS always had better internal energy than GJ. This was mentioned even during the initial encounter. After the skip, his energy improved greatly and his technique ascended a level. I think they're still roughly the same level, because even after the skip, he wasn't able to explicitly overpower ZBT.
The principle of ZBT having more internal than GJ may be sound, but ZBT has less stamina than GJ, so it is unknown how much that offsets.
