The one key difference is that many writers, editors, photographers, etc are full-time employees. They don't have better creator rights, but they do get a paycheck, vacation time, sick leave, retirement, etc. They are also expected to create work on time, a daily paper goes out regardless. You blow deadlines, you get fired. You don't get promoted or touted as being a great creator. Many of the fan-fave comic creators could not work for a newspaper, magazine or syndicate.
In fact, this argument began decades ago between Newspaper publishers and comic strip creators as in the early days, the cartoonists worked for a specific paper/publisher and not a syndicate. But, if the creator left the paper, the publisher asserted ownership of the strips which lead to some very familiar sounding lawsuits.
