Fat burner

Which one? T2 or MD6? Has anyone tried both and prefer one over the other. ( or prefer another product all together?) I’m down to the stubborn fat on the obliques (love handles) and can’t seem to shake it. Will one of these help or should I just cut my calories some more and/or increase my cardio? (is there such a thing as too much cardio? (as far as fat lose is concerned)).
