Would it be better to invest or pay down mortgage?

I am looking at either putting most of the money into index funds (spy, dia, vti, qqqq, etc.) or paying down my mortgage.

Which option do you all think would be better in the long run?

What are your goals? If you want to retire in 5 years, I'd say pay down the mortgage. If you want to retire in 30 years, probably the market.
