Is Using an American eBook Company Worth It?

[aimee]

I've been thinking about publishing my next book digitally, and I keep seeing references to different American ebook company options. Are these companies really worth it for new authors, or is self-publishing a better route? How do they handle distribution, royalties, and marketing compared to other platforms? I'm curious if anyone here has experience working with an American eBook company and can share insights on whether it made a real difference in visibility or sales.
