You can choose 1 of 2 things.
1.) And adaptation of a manga you really want to be adapted.
2.) A continuation of a series that was left to a "to be continued in the manga" ending.
You also have to consider a few things, how much money it would cost to start from scratch vs starting from the last episode of the anime before it ended. How big the fanbase of the manga is vs how big the fanbase of the anime that ended was before it went back to manga form, and lastly the overall quality of both manga series vs previously aired series.
