Are Amazon Self Publishing Services the Best Option for New Authors?

[aimme]

I've been learning about Amazon self publishing services and wondering if they're really the best choice for independent authors. The platform seems easy to use and offers global reach, but I've also heard mixed opinions about royalties, competition, and marketing. For those who've used Amazon self publishing services, was the process smooth and rewarding? Or did you face challenges that made you consider other self-publishing platforms instead? I'd love to hear about your experiences and advice!
