Bitbucket pipelines are very simple and YAML exclusive. It gives us more control.

I haven't used Buddy.works, I generally use Netlify for Deployments and notifications. In netlify you don't even have to write a yaml file. Just enter which branch and what command to run. CICD will be up and running in like 2 minutes.

Setting up Bitbucket pipelines takes upto 30 mins. You have to setup branching and everything.
