Axiom vs Expect


Just wondering if there is any major differences between the axiom and expect. I have an axiom now, just wondering if it’s worth updating to an expect.
It's worth updating because the expect is newer, I've tuned both better results with the expects, but that could just be because I've learned more especially with tires.
It's always worth updating to a newer kart as information is more current. Even so, the Xpect has more RF bite than the Axiom so it will turn better even if the setup/tires are off.
