People who say Fortuner is back killing must drive in BMW X7 or Audi Q8, and their opinions shouldn't be taken into consideration. Yes, Fortuner is less comfortable than Prado. But Fortuner is also brand new, has a significantly more powerful engine, more off-road capabilities, company-backed warranty and service, looks better and is generally a more modern vehicle.
If comfort is top priority, get a Grand Carnival or a Sorento.
