would the fact that the old inserter worked better unpowered indicate that the adapter is bad or something else?

The inserter contains a capacitor that lets the signals through to the TV with or without power, but blocks the DC power needed by the preamp.
Depending upon which channels are missing, if you get 20 channels unpowered and 9 powered, that might be a symptom of overload from your strong local channels.
