Not the easiest of comparisons I'd say. One is a replica of an iconic 'no frills' type bass, and the other fully luthiered with beautiful wood combinations and a really flexible EQ.
I've seen and played that ACG and it is lovely, although as a massive fan of things ACG it might not be the coldest of objective viewpoints. I'm not a massive fan of Fenders, but have been talking to Limelight about a yob bass myself (I'm a complete hypocrit really). Tough call, and I do get your dilemma.
As I so very nearly parted with cash for the ACG and haven't got to that point with Limelight, ACG is where my vote would go.
Probably no help at all really. Worth noting the 4-string ACG single cuts are very rare.
