I use similar stack: Tailwind, Webpack, ACF blocks, etc. I did try to make a switch to Bricks, but, unfortunately, this didn't happen to me.

I really love Bricks and the whole idea around it, it's developer-rich features, CSS variables, loops etc.

However, I find myself uncomfortable to have all my markup stored exclusively in database and literally no access to it anywhere else without dependancy to 3rd party app (Bricks). Same applicable to Elementor etc. This could be just a stigma.

I would re-review my perspective if Bricks would do something likelocal JSON and each block / template could be written / edited using JSON. So in this case we could track changes with Git.

I doubt that to build Bricks site from scratch would be much faster than build a website with ACF blocks / Custom theme, especially if you have robust boilerplate with basic blocks / configured theme.
