Room correction may make the sound better to your ears or it may not.
One issue is the target frequency response curve it is trying to achieve may not be to your preferences.
Another issue is that it will most likely try to fill in the valleys in bass response by boosting the frequencies. Boosting bass frequencies can quickly rob an amplifier of dynamic power and cause early strain and clipping.
I personally do not use it and if I did I would use it to eliminate peaks. However proper speaker and sub positioning can do that quite well.
