Here are the characteristics of each route:
Economy routing: This route offers low cost delivery. Features like control of the Sender ID, delivery status reports, local time stamps, Unicode messaging, and speed of delivery are given a lower priority on this route and are very often not available. Messages are typically sent via SIM farms and indirect routing.
Premium routing: This route is typically used for high priority messaging because it offers superior delivery and reliability. Other features include control of the Sender ID, delivery status reports, Unicode messaging, and local time stamps. Messages are typically sent through routes that have interconnect fees, or through direct operator connections.
Please note that these describe the ideal situation. Some routing options may have different characteristics depending on which country you are sending to. And in some cases, a country might have limited routing options, which means that the routes available could have exactly the same characteristics and pricing, or that there is only one route available.
