Higher revs when cruising typically mean poorer fuel economy. There is always a balance between economy and performance: you can't have both.

Yes, despite having precisely the same gear ratios, the FXT will reach the end of 1st gear before the WRX shifts into second, the end of 2nd gear before the WRX shifts into third, etc. However, because the output shaft spins at a different rate from the WRX to the FXT within each gear, the FXT will be able to climb through the revs quicker i.e. faster acceleration. So, although the WRX will continue to pull in first after the FXT has shifted into second, the FXT will be ahead of the WRX in a drag race. This accounts for the quicker 1/4 mile times the FXTs typically post (this is also part of the reason why JDM WRXs have quicker acceleration).
