Are AXS upgrade worth it?

[nv70]

I have old GX that works just fine. But was suprised how fast last casette was toast (and chain).
Goal is that maybe casettes last longer with axs vs my bad non electric shifting and less adjusting.
Was looking at a new gx axs upgrade kit w latest rocker paddle controler for 472€
