Does not say a great deal for the particular Samsung employees 😀 yes Smart Switch is the more convenient method. Seems an issue with the initial link, more details here https://www.samsung.com/uk/support/mobile-devices/how-do-i-switch files Bluetooth and NFC would be slow.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
