Earlier quoted context omitted.
I jumped to Netlify after I had my static site on s3 and thought to myself "securing it through letsencrypt could be nice" and after 3 hours I couldn't get it working, so I ported the site over to Netlify in ~15 mins including the lets-encrypt integration and pointing the domain over.
For reference you need to use Cloudfront to back S3 static sites (kinda sucky) to get SSL - We do that on prod but we also use netlify for dev (we could for both, but AWS existed before in out estate, accounting etc)
I don't mind AWS, but Netlify was just painless.
In similar fashion I use now.sh, I could upload a thing to s3 and fiddle with permissions and settings, or I could `now` :)
