Cost: magazines are definitely cheaper than agents. Because magazines only charge a small part of the page fee. On the other hand, the agency charges more.
Times: Magazine editors rarely collect their own manuscripts. After all, every editor actually cooperates with many agents. They will get the manuscript directly from the agent and extract some benefits from it. There are many manuscripts in the hands of agents, so magazine editors are generally happy to cooperate with them.
Comments: It is much easier to find an agent than a magazine. In other words, magazines are cheap, but there is no time guarantee and the review period is long.
Agent: The price is not too expensive, and the review speed is fast and the time is short. Most authors who need to publish papers now are pressed for time and papers are more troublesome.
