I like this better because you don't have to remember whether it's the attacker or defender that needs to be even for the adjustment to apply.

This has the same balance benefit of the original system (+1 effect per +1 improvement), but a weird artifact that half the people are worse at defending than they are at attacking, but others aren't, and whether they are not changes when they improve their adjDX.
