Ship Simulator Extremes my preferred on some reasons:
1. A bigger selection of ships.
2. Two ports in one environment for cross channel travelling (You know which one
)
3. Multiplayer is even more active than it's predecessor (Simple knowledge)
3. Close to realistic graphics.
4. Campaigns!
5. Working Ferry Ramps
6. The coming M.S. Oceana (Bonus!
)
7. Extending farther in updates than predecessor (SS08= 1.4.2, SSE= Continuing!)
8. Everything else to 100!!
