Maybe, maybe not.
Depends how big the DB is, how long it takes to backup full, diff or log, how long the restores take, what the downtime allowance of the DB is, how much storage space is available, how long backups are retained, how much of a performance impact the diff backup has, etc.
There's no absolute right or wrong answer.
