Info to start FPP

[gb70]

Hello everyone,
I couldn't find the introductions section: my name is Graziano and I'm Italian;
sorry if i don't write correctly in english form.
I am still inexperienced as I only started three years ago.
I have some synchronization problems from the PC and I would like to take the road with Falcon Player.
Currently I run the show with an "old" PC connected via LAN cable to a router dedicated to the "CLS", I have installed Vixen and I'm using WS2811 pixels (I have just over 4000) managed by 6 ESP32 "with espixelstick" in wifi.
I already plan to insert another 2000 pixels next year and later I would also like to insert P5 or P10 panels.
Unfortunately I couldn't find a post to see if it's any better Raspberry Pi3/4 or Beaglebone Black?
Can you help me?

Thanks in advance for the long read and for the answers.
Graziano

I do not use an panels so no info on that.  I am not sure there is a right/wrong answer to the Pi/Beagle Bone question.  Right now I would think availability would drive your decision.

Thanks, K-State Fan, I'll probably go to the BBB.
Since it's my first step into this world, do you have any advice on how to get started?
Thanks.
Gaziano
