Depends…
They’re both lossless so there’s no difference in image quality.
The up to 50% difference in size is due to deflate (zip) compression that is built into PNG, but optional for TIFF. You potentially pay w/ slower I/O to compress/decompress, if that is of any concern.
Other than that, the PNG spec was kind of vague (and changed recommendations) on how color space signalling should work (not to mention Exif), so PNG color management and metadata might be spotty w/ some 3rd party SW.
P.S. Looks like you started a similar topic already?
