Yes, you are comparing apples to oranges. Comparing just comparing size alone.
Both ships will offer the same amenities although I dont think the Triump has a specialty resturant. Both ships will have two shows, comendians, piano bars- 24 hour pizza and rooms ervice.
The valor probably costs a lot more since she is a very new ship. You didnt mention how much of a price difference there was. If its a huge difference-book the triump and in a few years the Valor will be cheaper.
