Most of these "technologies" are not proprietary to Anker or any other charging brand, just fancy names for features that are already part of the USB power standard. Qualcomm QuickCharge and other charge technologies that go beyond the USB port are different and require both the charger and the device to cooperate with each other, those are proprietary.
If your phone accepts a 2.0 amp maximum input charge, then any 2.0A or the now more common, 2.4A, charger will provide the fastest possible charge. If the output ratings are true that is, and most likely they are. VoltageBoost and all are most likely a gimmicky name for something already found in the USB charging standard. Any USB charger (that meets the proper standard and meets or exceeds the max input amperage of your device) will "intelligently" charge your device. Sure there are other factors that affect charging speed/reliability like cable gauge, so it's always good to invest in a nice USB cable that can actually keep up with the current.
