There is no single best platform, only the best fit for your goals and budget. Here is a straightforward comparison.
Website builders (Wix, Squarespace)
Builders are inexpensive ($16 to $49/month) and quick for very simple sites, but you are limited to their templates and features, and you do not truly own the underlying code. They work for a basic presence.
WordPress
WordPress powers a large share of the web for good reason: it is flexible, SEO-friendly, and easy to update once it is set up well. A custom WordPress theme gives you a unique look with the freedom to grow.
Custom build
For online stores with special requirements, web apps, or unique functionality, a custom build gives you exactly what you need with no platform limits. It costs more upfront but scales without compromise.
