It's not really the same question... because with Verion Fios the question is only about the Router (modem is a Fios device that you can't really buy, and they do not charge you for it) while with your Optimum you're looking at a modem.
You certainly want a device that they officially support (I believe there are many more officially supported devices, not sure where you got those 3). You can have both in one (like the Arris TG1672Gor the SBG7580-AC) or you can have a separate modem (in the SURFboard line, like the SBV3202) and use whatever router you want.
