If you then move to a RT kernel then both becomes the same (more or less, at least this was true the last time I checked).
Snakeoil is designed to run headless - i.e. no keyboard, mouse or video and everything is done remotely. This does gives the sound quality and edge. No GUI means no graphics, which reduces the load overall (less current drawn).
Having said that, there's every intention to create a text console UI. This is still in the pipeline, and I'm thinking of using Golang for this - this will come in time......
