It is possible for a 4 cyl to have better VE than a 6 cyl. I am not familiar with specific Nissan engines VE to state conclusions without looking them up.

Torque curve is not "powercurve", as power is not the same as torque. Torque is a defined measurement of pound-foot (not foot-pound) .
Power is how much work can be performed in a specific time period.
I am going to use actual numbers wo we understand each other.
If one motor (2.4/ starts building boost at 3k) makes 480whp 470wtq (built block stock head) and redlines at 7.5k
The other (2.0/ start buildng boost at 4k) makes 480 whp 390wtq (fully built on race gas) and redlines at 8k

Which one you believe has a better powerband?
Which one you believe will have more boost lag?
Which one would you chose to make 700whp?
