SHORT ANSWER
Use an IC card as the flexible baseline. Add a subway pass only when your planned rides are mostly covered and the current pass math works.
STRONGER FIT
- Mixed rail/subway itineraries
- Travelers who change plans
- People who value tap-and-go simplicity
CHECK FIRST
- You assume one pass covers every Tokyo train
- Your route uses several operators
- You have not counted ride days and coverage
