Here it is much closer than if we compare RAW vs JPEG (where RAW is clearly much better).
However, in this case RAW also has a clear advantage over TIFF.
The main reason for this is that by directly stacking RAW files Nebulb works in the camera’s internal color space (as the camera registers colors). And precisely for this reason, after stacking it is possible to modify the white balance completely to your liking and it is also possible to apply a highlight recovery (things that cannot be done in the same way with TIFF).
