Also let me add to my above reply that I use both styles & tracks depending on the arrangement of the song.....
As a singer who uses these styles and tracks to "back up my vocals" which is the most important part of my act...both have their strengths and weaknesses for different scenarios.
And it's good to have more then one tool in your box on stage to get your song across..to limit yourself to only one way isn't my cup of tea.
