I avoid using speedbrake to the maximum. The buffet is uncomfortable and they usually reveal poor descent planning.
On the 320 the managed descent usually leaves me below profile
I like to use VS mode, It is more comfortable, if im confronted with having to reduce speed i activate the approach phase getting rid of the speed bug or simply select a lower speed so i dont have to worry about the thrust increasing,
I control the speed with a combination of VS and speedbrake if required.
If above profile i press EXP DES down to 5000 if required ATC permiting. The extra drag from high speed descent really helps to capture the profile.
