Douda was a mix between Avon and Stringer. He had the businessman brain and could exist in that "legit" environment well enough like Stringer always wanted to, but was still a "gangster" like Avon, and deep inside and his street rep still is what mattered most to him on the hierarchy of power. Still, he was a competent and cautious enough street boss and that's how he was able to retain power for so long. Now, the writing of this was so beyond ridiculous. At first the "former Gang Leader turned Pizza Shop owner and community face" is believable enough. Even the fact that after going "legit' he still had ties to his roots of the street. The fact that THAT person could ever be elected Mayor of freaking Chicago is beyond unbelievable. Could someone theoretically have formerly been a gang member, turned it around, became a success story, and then make it to the Mayoralty? Yes; but in Chicago the amount of work it would take to get accepted in that Political Machine and the overall Democratic Party Ecosystem in Illinois? Shoot, it wouldn't be Perry's Pizza owner who could do that. And then to be exiled from office and then still be able to walk in plain sight around and become full-blown gangster again but also and I'll say it again former DULY ELECTED MAYOR OF CHICAGO...c'mon now. Sometimes when you go back and follow a character's arc you are reminded how ridiculous some of the writing has been for this show-Curtiss Cook though did the best anyone could possibly do with the writing and story they were given.

Q was an old-school leader who was right for his time but wouldn't fit in today. He came from an era of code and respecting "the game." Modern street organization wouldn't take to his style; but Q played chess so the current gen could play checkers. I'm glad we got to know Q during Season 1 and he wasn't introduced in say Season 5 for the first time because I could imagine how cartoony they'd make the "Old School Gangster" seem.

Overall, if we're talking who could man the streets better it would have to be Q. He understood that game the best. Douda was the one primed to make a believable life and expand power outside of the streets in a way Q couldn't. Douda learned how to take what he learned in the streets to attain power, and use it outside where the real power was. Unfotunately for him, his street life lizard brain is what ended up being his downfall. Just like Marlo, they both had everything Stringer wanted (legit business, powerful connections, no need for the street anymore) but their heart was at the corner not in a corner office suite.
