8-bit Blending takes 8-bit jpegs as input and outputs an 8-bit image. HDR Merging takes 8- or 16-bit images (RAW) and builds a 32-bit image. From that HDR image, you can output a 32-bit Open EXR or a 8-bit tone mapped image (JPG or TIFF). Open EXR is a floating point format, carrying much more information than even 16-bit RAW images. Every single bit of dynamics is preserved with this process.
