Are full range of motion or lengthened partials better for building muscle and strength?

Full range of motion and partials are two methods for varying your lifting, which involve manipulating the distance that you move the weight. Research generally showed that full range of motion is better than partials, but recent research has started to change on this subject. Recently, the training of “lengthened partials” came around, and shows us that actually, partials may sometimes be better than full range of motion.
