Good pickups do make huge difference and they are better,
it's kind a hard for me to say if YOU really need to change them.
Problem is this, not every piece of gear reacts the same,
with tube amps and preamps you have better response, dynamics etc,
you can really hear everything that is coming or not coming from the pickups.
With digital units is so much harder imo and most of the time we are "blind" there.
I would bring your guitar to a guitar tech and measure the output,
then he'll be able to say how much power those pickups actually have,
maybe give you some advice , recommendation etc.
I give that kind of advices to my students in private here and there
but ONLY after I try guitar myself, it's hard to tell without any checking indeed.
