I know that nidoking is better than rhydon, but what about rhyperior?
My team (yes I'm a gen1 fan):
there's not really a right or wrong answer in these types of questions. But based on the types and weaknesses I'd have to go with nidoking. Both of them get good movesets. but rhyperior has 3 4x weaknesses (being ice, water and grass) and 6 weaknesses in total while nidoking has 0 4x weaknesses and 4 weaknesses in total so based on my opinion i'd go with nidoking
