Both are same but, Asymmetry is qualitative and tailing is qualitative as well as quantitative.
e.g.
1) Asymmetry ( Peak is symmetric or asymmetric)
2) Tailing factor ( If asymmetry factor greater than one then that peak is Tailing, If asymmetry factor less than one then that peak is fronting)
In tailing factor u can tell ur peak is symmetric or not( if not the how much ur peak is not symmentic)
