The decision boils down to… do you need a differential backup every 4 hours if the need for log backups every 5 minutes overrides that to a certain degree?
From reading about differential backups, in a restore situation you would have to restore not only the diff backup but also the full backup so more effort hence why if I was asked for 3 answers I would go with CDE.
