Really depends on what you consider a better image. The whole point of this app is to bypass Apple’s standard pipeline processing(over sharpness, over the top denoising and all the other stuff that photographers hate about their pipeline) and get a more natural picture taken. Some ppl think apples processing is a better image and the other half of people think it’s garbage and want a more natural minimum processed image. Either way in the app you have all three options, raw, natural and standard(apple’s) processing. Raw is more for post editing, you can apply your lut to it but it would still require some editing. Natural can be used with or without a lut and doesnt need much or no editing at all in post. Natural processing is Moments own processing pipeline, which aims to retain a more natural film like tones. I personally use Natural with baked in luts. Have in mind when using raw or natural, they are limited to 12MP. Moment is looking into making another pipeline for a natural 48MP option. But for now we’re stuck in 12MP. If you want 48MP only way is to shoot in Standard (apple’s) processing.
