Abstract: The need for accurate and precise polarised parton distribution functions (PDFs) is becoming increasingly crucial in view of the Electron-Ion Collider experimental program foreseen in the coming years. Two global PDF determinations at next-to-next-to-leading order accuracy have been recently presented, MAPPDFpol1.0 and BDSSV24. I review the former and I provide a comparative discussion of other PDF sets accurate to next-to-leading order. I show that differences between these PDF sets, due to the choice of experimental and methodological input, exceed differences due to perturbative accuracy.
