When learning a new language it is often difficult to master the little details. Swap out 'has' with 'have', 'its' with 'their', 'other' with 'others' and it changes to:
"All the services have their advantages and disadvantages over others"
Each of these differences may appear significant to a native speaker, but the basic meaning of each word is almost the same.
