@vivianrose @syntacticsugarglider from experience the various aliexpress strips are okay quality.

However, SK9822 / APA102 are similar strips but with a few important improvements; they have a separate clock line so they run better over longer distances, and their PWM is faster, so they appear to flicker less (especially when you move your head while looking at them), which to sensitive people can be quite distracting
those are a bit more expensive than ws2812 however, but imo worth it
