The Touch ID is less secure because you can force a person to put their fingerprint to unlock their own phone. Forcing the passcode out of someone can prove more difficult and the phone will wipe itself after 10 tries (if you have that feature enabled). I could steal your phone and manage to unlock in the process by taking your hand and unlocking the phone before walking away, somewhat more difficult to do with a passcode.
