There is no one-size-fits-all answer to this question, as the best traditional publishing company for a given author will vary depending on their individual needs and goals. However, some factors to consider when choosing a traditional publishing company include the size and reach of the publisher, the quality of their editorial team, their marketing and publicity capabilities, and their overall reputation. Additionally, it can be helpful to seek out personal recommendations from other authors who have published with the company before making a decision.
