WS2812B - Microchip or Atmega ?

WS2812B - Microchip or Atmega ?

I need to control 300 WS2812B LEDs (5 meter) Before I start developing a driver board I need to know which chip I should use for this project.

I have read that the younger Microchip devices such as the PIC16F1509 are fast enough to control 300 WS2812B LEDS. Or should I use an Atmega328 ?

Maybe there are other “better” devices for this project.

I've used an Arduino Uno 328p with success, but bear in mind the limited ram might cause problems with longer strands of LEDs.
I've been trying to get at Attiny85 working- it works beautifully with a 60 led strand using adafruit's strandtest (power from 5v pin on a digistump board) and also Josh's code see https://www.google.com/amp/s/wp.josh.co ... -them/amp/ yesterday I got this to compile ( but not work) as supplementary code. This technique has the advantage that the contents are not buffered in ram so longer strands can be controlled.
