Lemfo LEMP 1GB/16GB vs Kospet Prime s wich is best?

Like in topic wich is best smartwatch? Kospet or Lemfo? The specification is the same but what about performance and possibility of modifications? Root and other mods.
PS. Is there a full android smartwatch with nfc?

I can neither recommend the Prime s nor the Lemfo Lem p, as both are Android 9 devices. I would strongly recommend an Android 10 Watch. There is currently no watch with NFC.
