> are flicker free to my eyes

Very rarely will bulbs visibly flicker in my experience. What happens instead is after several hours I'll start to get headaches and feel fatigue without knowing exactly where it's coming from. Since I replaced my Hue bulbs (which flicker, and I proved it by just using my smartphone camera even) I've felt so much better at home

all bulbs have some flicker, and the fact that it resonates with your phone screen's refresh rate or your camera sensor's sample rate doesn't really mean anything.

No, if you spend money on a good LED and get a photodiode hooked up to an oscilloscope, you can quantify the flicker. The good LEDs will have absolutely zero.

I second the A19 and other bulbs from Ikea. I live right next to an Ikea and it turns out their bulbs are pretty good. Even the housing feels better than Phillips or others.

I used to have an expensive Phillips light alarm and it flickered like no other. Especially if you lower the dimming you'll tend to see more flickering or just notice an "ick" feeling with crappier bulbs.
