UXR who can do design or UXR who can do heavier quant?

Hey all! I’m a mostly qualitative UXR with a stable job and I’m looking to upskill.

I’m deciding between investing more in product design skills or going deeper into quantitative research. I already do some light quant work and see mixed-methods research as a must, but design also has more opportunities, especially freelance.

If you were in my position, which would you focus on: design skills or stronger quant skills? I actually enjoy both and am willing to invest to become good at it.
