Diff Drop, Yes or No?

I am researching what kind of suspension to go with. I'm pretty sure I going with a 3" and was considering what all I need to do and came across this video. Checking to see how you all feel about this.

I’ve read that helps a lot for when you’re at full droop. That’s when the cv axle binds and the speed of the axel causes it to snap when off-roading

 

I took the diff drop out, but I'm only around a 2" lift. Seemed that the front end was a lot more "growly" with it in and I didn't like the angle it was putting the front drive shaft at. The angle of the cv's seemed negligible for normal use.

This is probably a more realistic reason as to why you would need one.
