Dynamic Window Approach(dwa) should be false ? true ?

Hi, I'm using nav stack with both of my robot and turtlebot.
I have a question about dwa parametor.
Can I set it false ?

Without DWA, the robot moves fast(it's natural) and smoothly,
and can avoid obstacles correctly.
Also, turtlebot's dwa parametor is false(default) though wiki says nav stack uses dwa algorithm.

Don't we need to use DWA algorithm ?
If yes, what kind of algorithm is used as local planner instead of DWA?
