Jeevan Mitra Triple Cover OR PPF+term paln?

i have just started investing in Jeevan Mitra Triple Cover for 7 lacs SA for 30 years and paying 28531 per year.

if i drop this policy and invest in PPF (19.5k) + term plan for 30 lacs by paying 9k per year

will i get better return in it or in above one? .

what would be aprrox return in both case?.
