I’ve shared most of my opinions on this before in the forum, so I’ll leave my comments to those posts.
But, to add something new. It’s important to remember that Bubble excels as an app builder, not as a static site builder. Knowing how to point domains to multiple places (ie. acme.com to WordPress, app.acme.com to Bubble) is the biggest hurdle (which is a pretty small one).
Some sites (like Wordpress, Wix and SquareSpace) are great for really quick development of static sites with minimal need for having a CRUD database. Webflow is great for pixel perfect static sites, and is getting better from a flexible database standpoint (but not much better).
My belief is that a static site is easier to maintain and launch on a platform that excels in that. (Ie. SquareSpace makes responsive design significantly easier out of the box). Getting Bubble to function well for static sites is certainly possible (and has plenty of advantages), but may not be worth the added time cost of building a static site on a platform that specializes in static sites.
