Best Metallographic Polishing Pads for Sample Prep?

I’m refining my sample preparation workflow and focusing on the polishing stage, where pad choice significantly affects finish quality. With hard and ductile materials alike, the right metallographic polishing pads help remove fine scratches from earlier grinding steps and improve surface flatness before etching or microscopy.

I came across this reference covering pad types and applications: https://ukam.com/product/smart-cut-polishing-pads-for-metallography-sample-preparation/

For those with hands-on experience:

What pad materials and backing types have given you the best balance of cutting action and surface smoothness?
