As we know SK6822 RGB LED and WS2813 RGB LED are both dual signal RGB LED with driver IC inside leds, and they have the same function when using. If any one pixel broken, will not effect others to work well.But, you may have a quiry, how i know which one is more suit for my demands?

1> Recognize them from picture looks, and you will find see the difference.

the SK6822 LED only have IC inside the 5050,  but WS2813 LED Have IC and Resistors, capacitors Inside the 5050 LED.

That is to say, there will no need to use any resistor for WS2813 LED Strips .

but for SK6822 RGB LED Strips , the resistor is needed.

2>SK6822's good point is it pass signals even if one chip is dead.

And bad point is it goes blue if there is no signal

WS2813's good point is it pass signals even if one chip is dead and it doesn't goes blue if there is no signal.

Thus you can choose the one you need for your demands according to the above difference.
