Sentai is indeed a genre (more precisely, a subgenre) of tokusatsu, but it has nothing to do with PR and was established back in the late 70s. The whole point is in the name. Sentai is a combat team in translation, so all team tokusatsu are usually called sentai. But neither Ultraman nor Kamen Rider in their pure form naturally belong to them. But Rescue Fire or Solbrain are.
