What is the opinion of Reddit about the
OEM Profile PBT RGBY CMYK Modifiers 10 Keys Laser Engraved Keycaps Mac Keycaps for Cherry MX Mechanical Keyboard (RGBY Mac Top)?

I recommend finding a base set of PBT keycaps from somewhere like kbdfans and then buying a mac modifier keycap pack after the fact.

This seems like an okay set of modifiers once you find a base set.
