Tony ended up being far more powerful then Frank. Remember, Tony ended up securing the direct importation of massive amounts of high quality cocaine via Sosa. And also Frank even admitted he preferred to stay under the radar for law enforcement so he was very low key. He also brought up what other king pins Would think if Frank imported all those Kilos from Sosa, so that means that Frank was also below Gaspar Gomez and the Diaz brothers. But at his peak Tony was the top dog.
See, I consider guys like Frank to be the more likable characters in such stories. Yeah, he went out like a bitch, but the guy survived on the streets for twenty years prior, had plenty of material comfort, and didn't die a drug addict junkie fuck. What'd Tony last, three years before getting popped off?
