I just bought my ppu digitizer two days ago! Very excited to get that working.

There are a couple reasons you would go this route or classic nesrgb, and I was very tempted (I might still do a nesrgb on my other nes, if ppu digitizer goes well).

Primary one is lumacode is a digital signal that requires interpretation before it can be input into a tv. You can use the creator's rgb2hdmi which requires a raspberry Pi, or you can use a scaler like retrotink or ossc (pro). An RGB connection is standalone in many setups, and also works with scalers. If you want to interface with a CRT, lumacode doesn't immediately support that.

Additionally, ppudigitizer doesn't (directly) support multiple palletes. You are stuck with whatever your lumacode interpreter provides (though you could in theory change this yourself).
