apparently BT versions 5 + are much better with lag - I tested with some BT v 5 headphones and the delay is imperceptible
Mini PC has v5.2
My RPi 3 only has BTv4 where as RPi 4 has v5
Can anyone confirm if it is indeed better or not ?

Have you already tried to reduce the length of the bluetooth buffer in Moode? (see menu "m => Bluetooth" or "m => Configure => Renderers => Bluetooth Control")
The second item under "Audio output" allows you to select the audio buffer size which is "500 ms" by default. If you set this to the minimum of "20 ms" and reconnect to your bluetooth device the lag should be considerably shorter. Note that although the option is called "output buffer" it actually affects inbound connections as well.
While 500 ms is a good standard setting for audio only transmissions (for stability reasons in case of a weak bluetooth connection), 20 ms is more appropriate in case you want to watch a video while sending the output to Moode. At least for me this largely fixed the lag when I connect to Moode from my phone (via aptX codec) and watch some YouTube video.
Best regards
