As per a different comment if you are worried about page load speeds you have some options, you can use Wordpress as your CMS in a headless manner which will let you cache pages for future visitors.
Then don't restrict your comments like that. WordPress pages don't gather 8000+ spam links because it's only capable of accepting wordpress users' comments.
WordPress is flexible enough and rich enough in plugins and themes that I wouldn't it an alternative to "building my own website", but rather as one technology you can use to do that.
