If only you'll be editing the site, as a dev, I always like to roll my own. Simple HTML/JS/CSS. Feel like I have more control, less learning and I enjoy it. But that's the dev bias.

If you want other non technical people to edit or make changes, choose a CMS.

Your goal is to get your message out there asap so you can solve problems.

End of day, the customer doesn't care, only you do. You can always change it later.
