What do you mean by : "So my question to the community is; Is it possible to use the marketing automation capabilities of HS with a decent website builder?"
If you are "not happy" with HS CMS, you can still use HS Marketing with wordpress or whatever CMS. At the beginning there was no HS CMS. You just need to be careful when deploying HS Tracking code on your website.
But yes, you'll be able to use HS Marketing Automation on a website hosted somewhere else.
