Backspin - center ball - topspin all affect the ball flight, which is how and why they should be used.
Example of a situation where backspin is beneficial:
Bethpage Black #1 with a tailwind. Because the fairway is 30'+ below the tee, adding full backspin will increase the carry (the distance before the ball hits the Earth), the elevation change allow the ball to carry additional yardage, and the tailwind adds more yardage.
When teeing off on BPB #1 with a 10 mph tailwind, full backspin will allow me to pick a spot on the fairway past the dogleg to land the ball. In those conditions, a 300 yard ball flight is common even though my driver is only rated for 270.
While the ball may carry 300, there is virtually no roll out once it lands.
A center ball drive might also travel 300 total yards, but in those conditions, only 275 will be carry and the last 25 will be roll. This isn't enough carry to cut the corner of the dogleg and will plop me into 30-40% rough.
Backspin will amplify the wind effect. If I have 52 yards to the hole and a 20 mph crosswind, I have 2 choices. I can either punch my 60 yard wedge 49-50 yards or I can take a full swing and try to draw the ball back to 53.
In this situation, the punch has a lower ball flight than the full swing so it's less affected by the wind. The backspin/full swing option will result in amplified wind effect because the backspin causes the ball to fly much higher. For this shot, I have much more control by punching the wedge 3 yards short rather than adjusting my aim 10-15 yards to try to get it within a yard.
My point is, every situation is different and requires a judgement based on a number of different factors. To say "I always do this..." or, "I usually do that..." only limits what you are able to do.
