Who Do You Think Are the Top Self Publishing Book Companies for New Authors?

Hey everyone, I have just finished my first book and I’m now researching the top self publishing book companies to help me publish it professionally. There are so many options claiming to be the best, but it is hard to tell which ones truly deliver quality results and genuine author support. For those who’ve already published their books, which company would you recommend and why? I love to hear your honest suggestions and experiences.
