Let's start with the Half Cross stitch. I use this stitch the least of the three. I don't particularly love it because it doesn't offer much coverage on the back of my canvas, which is important for structural longevity. It also is not any easier than the continental stitch. There will be times when I'm switching rows, or dealing with a motif, where I need to do a half stitch, but for the most part, I use others.
