Do you have a product that you would call your holy grail lip product?

I assume I have an autumn warm undertone, and I think I've tried a truly wide variety of lip products since my early 20s, when I was incredibly interested in cosmetics. Among them, the shade I would call my "holy grail" was MAC's "Korean Candy." When I applied it, I really understood what it meant for a fluorescent light to turn on. My only regret now is that I didn't stock up on it when I heard it was being discontinued. Lately, I've been wearing Hera Pampas, but I'm wondering if there are any better products out there. Do you guys have a holy grail lip product? Please share it with me!
