I think I'd prefer to see a slightly more rigid/formal Starfleet.
Both Kirk and Sisko certainly ran tight ships.
On Kirk's Enterprise, military decorum was observed. Military customs and courtesies were employed and there was a definite military chain of command. With few exceptions the crew were referred to by their rank and last name. They were in clean uniforms, males were shaved, their hair was off their necks and (except for Chekov) reasonable short. When Kirk gave an order, he expected to to be obeyed.
Starfleet is a military structured organization. When Kirk took Spock to Vulcan in Amok Time, he fully expected to lose his commission.
While might be some debate about the use of the term
"military," there no doubt that Starfleet is the uniformed armed forces of the Federation.
Also, while Bill Adama may have run a rigid command deck, what was going on below decks on his Battlestar was a absolute mess, as Commander (later Admiral) those problems were his responsibility.
Battlestar Galactica has to be one of the worst examples of a military ship ever to be seen on TV. It was pathetic.
