Switching to Optimum Online; What are the Positives/Negatives? Is it worth switching?

I currently have Verizon DSL for over 10 years. They ONLY offer 1–3mbps “in my area” (15 min outside NYC). No FIOS, no “fastest” no “ultimate” packages for 10 years. So we want faster internet with all the people in this house streaming netflix, youtube, 5 iphones, 4 computers etc.

Optimum advertises 15mbps for nearly the same price! I looked up some reviews for optimum service online however and almost ALL seem overwhelmingly negative. Now we don’t care about the “optimum email/homepage, or even the customer service as a MAIN concern. We have everything set up, but are their any Optimum Online customers that say their connection speed is AMAZING and well worth it? are any of you getting the 15mbps!? I am considering cancelling the installation after all of this research! Thanks guys!
