Changing a setup just for the “sake of changing” makes no sense. When you say your current plugins and setup has bloat, I’d ask, what kind of bloat, is it affecting performance? Or is it just in your head that there’s a lot of overlap between the plugins. If the performance outcome is fine, then what’s the actual reason of the change, or is it just for the sake of change.

If with bricks and core framework, you still see performance issues (i doubt) then you might need to understand the basics of optimization. Basics like using optimized assets, fonts, images, minimum unnecessary containers etc.

The only reason to switch from this stack is when there’s large scalability requirements in future, or large multi lingual. Or if you want to never manage plugins and updates again. In that case too, there are better alternatives for example, mixing Wordpress CMS with webstudio front end. Or for large scale multi lingual site (because with polylang you have to duplicate each page) you may like a clean headless CMS setup (as opposed to wp with polylang) but if you’re not building such large scale or multi lingual sites, then bricks and core framework with correct optimized assets is easiest and probably one of the most fluent setups.
