Is Hiring a Professional Cover Service Worth It?

I’m exploring options for creating a unique cover for my new book and came across several top-rated custom book cover services. Do these services really make a difference compared to DIY tools or freelance designers? For authors who have used them, was the investment worth it in terms of quality, reader appeal, and sales? How do you choose a service that delivers a professional and eye-catching cover without overspending? Any experiences or advice would be really helpful!
