There is no Exif metadata filed called 'Date Taken'. Date Taken is a Windows property that looks a photo's Exif, XMP, and IPTC date metadata to determine what to display as the 'Date Taken'.
If you are certain that the photo you want to sort were taken with a digital camera and have intact Exif metadata, the date displayed in the Date Taken field will be reliable.
Although Exif DateTimeOriginal is the best indicator of when the shutter was pressed on a camera, Directory Opus (and Widows File Explorer and other applications) will display a Date Taken even if there is no Exif DateTimeOriginal or Exif CreateDate.
I am a professional photo organizers, and I work with large collections that may include photos that have been scanned, or have been stripped of their Exif date metadata. A important step in organizing collections is to separate out photos that do not have complete and intact date metadata.
To do that, I use the ExifTool Custom Columns script so I can view many different date metadata fields.
