Once you've used a couple more static hosts you'll find that gh pages is a second tier host at best. Lacks some basic configuration options and toolings, can be very slow to update or deploy, the cdn actually isn't as good as others, etc. Github pages is great for hobby projects and if you're happy with it by all means keep using it... but I wouldn't ever set up a client's production site on it.

If you're curious, Netlify is one popular alternative that is easy to get in to even without much experience. I would say even at the free tiers Netlify is easily a cut above Github for static hosting, and it hooks into github near perfect straight out of the box if that is something you value.
