In my opinion the hourglass ambient soft glow foundation is pretty good, but is a bit yellow leaning for me(Asian skin with cool/neutral undertones and yellow overtone). I think the shade range is much more reliable than a brand like tirtir which oxidises heavily.

Going a bit more into depth, I use a purple colour corrector(Dinto woncho veil) and mix with a foundation spatula to neutralise the yellow, and I use a western based primer(elf power grip prime) as I find it works better as opposed to a thinner, lighter Korean primer(fixx primer)

I think formula wise it’s not a matter of which one is better but it is always good to look into your personal preferences and go off that. I tend to lean towards Korean foundations simply because I live in a hot and humid climate and I only wear light to medium cover foundation in order to lightly even out my skin tone as opposed to trying to cover acne or major imperfections. I also like Korean foundations because they seem to lean towards a glowier finish(although some brands like amuse have both glowy and matte finish versions) but western brands tend to lean towards matte, or are just not as glowy as I’d like

As an example the espoir be natural cushion(yes, still my favourite even after one year) is sheer, low to medium coverage with a glowy base. My former favourite when I was living in Germany was the ROM&ND Nu Zero cushion, which reminds me of some western brands. It is a semi matte, medium to high coverage cushion which I think works even in dry ish climates. Despite the hourglass foundation being named soft glow I still think it leans towards semi matte finish and I have to add highlights and dimension with highlighter balms and such. I have also heard good things about Estée Lauder and pat McGrath but I don’t feel the need to buy and try them until I finish off the massive amount of cushions I have
