Pi 3B+ - 3.5mm or USB audio... which is better?

Hi Chaps

Which provides the better audio quality - the onboard 3.5mm audio jack or a separate USB 'dongle' from the likes of eBay?

Is the 3.5mm audio PWM or is there a dedicated sound chip on the Pi that handles it?

The audio jack is PWM not the greatest but works. USB will be the best option or a I2S from Adafruit since it has a built in amplifier

Pwm audio is noisy, usb audio is definitely the better option but you might want an amp too go along with it if you use a speaker
