I've been using Sensodyne Sensitivity and Gum for years and never contemplated anything else because I was so satisfied. The white paste has now been reformulated into a blue gel which is horrible, awful, unusable. It stays in a lump while brushing so at the end you spit out half the gel in one glob. By the time you get to the end of the tube, the remaining gel has firmed up even more and is impossible to spread around your teeth. Did they even do any market testing? I can't buy this ever again.
