The whole idea of net neutrality is that content creators can't pay ISPs for preferential treatment. This means that the large ISPs won't be receiving payouts from Netflix and suchlike, and therefore won't have an advantage in this area over smaller ISPs.
If you really want to push for competition, there are other options. I don't know much about the situation in the US, but in the UK we have local-loop unbundling (LLU), which has proven to be a success in driving forward competition in the ISP market.

LLU helps smaller ISPs to compete with larger ISPs, as it allows them to build up their infrastructure without duplicating the work of laying cables. From the Wikipedia page I just linked to it appears that LLU is at least legal in the US, I'd be interested to learn about how popular it is.
