DEST vs DLIB

Quick question, will both DEST and DLIB give same output? Also, which will be more accurate.

Good question which I cannot answer thoroughly. However, both DLIB and DEST have been applied to the same video.

I don't know how DLIB video was made, but for DEST the following procedure was applied. Viola-Jones algorithm was used to determine a bounding rectangle containing a face. Regression was then applied to this rectangle. Since Viola-Jones takes around 50ms per frame, DEST uses the regressed frame of frame n-1 and uses that rectangle to initialize the bounding box for frame n.
