If Anakin never turned, there would have been a very different outcome. The balance of the Force could have been maintained, and the conflicts that led to so much suffering might have been avoided. Also, Anakin's relationships with other characters, like Padm茅, would have developed differently without the influence of the dark side.
If Anakin hadn't turned, the Sith's plans might have been foiled. The balance of power would have remained with the Jedi, and galactic conflicts could have been avoided or resolved differently.

If Anakin never turned to the dark side in the fanfic, the galaxy would be a very different place. The Clone Wars might have ended sooner, as Anakin's strategic brilliance could have been fully utilized for the good of the Republic. He would still be a symbol of hope for the Jedi and the people of the galaxy. His friendship with Obi - Wan would have remained strong, and they could have achieved great things together as a team of powerful Jedi.
One possible plot could be that Anakin continues to be a Jedi and plays a crucial role in bringing more peace to the galaxy. He might focus on training new Jedi, using his unique skills and powers for good. For example, he could be sent on diplomatic missions, using his charisma to convince planets to join the Republic without the need for military force.
One way to write it is to focus on Anakin's positive relationships. For example, if his bond with Obi - Wan was strengthened even more, it could prevent his fall. The fanfic could show more of their training sessions together, with Obi - Wan guiding Anakin through his inner turmoil in a more effective way.
Anakin not going to the dark side could have prevented many conflicts. Maybe he would have found a way to peacefully resolve issues instead of resorting to violence. It would have changed the course of the entire Star Wars universe for the better.
His relationship with Obi - Wan would have been much more positive. There would be no betrayal, and they could have continued to be master and apprentice, or perhaps even equals as they both grew in the Force.

He would be seen as a more stable and reliable Jedi, and Yoda might have given him more responsibilities within the Order.
Well, if Anakin never turned, then the Sith's long - term plan would have been in shambles. The Sith had been plotting for a long time to take over the galaxy through Anakin's fall. Without that, the balance of the Force would have remained more in favor of the light. Anakin could have been a great Jedi Master, training new generations of Jedi. His skills and power on the light side could have been used to fight other threats in the galaxy. And there would have been no need for Luke to redeem his father, as Anakin would have always been on the right side of the Force.
