SRAM NX vs GX crankset: noticeable difference in weight, stiffness & looks?

Hey everyone,

I’m currently running a SRAM NX crankset, but the rest of my drivetrain is already X01 / XX1, so the NX cranks are starting to feel a bit out of place.

From a performance perspective, I feel that reducing weight directly at the crankset could improve responsiveness and pedaling feel, even if the difference isn’t huge. That said, I’ll be honest — a big part of this upgrade is also aesthetics, since NX doesn’t really match the rest of the build anymore.

For those who’ve gone from NX to GX crankset:

Did you notice any difference in stiffness or pedaling feel?

Is the weight reduction noticeable in real riding, especially on climbs?

Any durability differences long term?

I’m also considering GX Lunar, and I’ll attach a photo of my bike.
Do you think Lunar works well with this frame color, or would black look cleaner?
