Well, using the aforementioned add-ons is way faster IMHO.

Have you ever given a look at Vivaldi browser? That is power user tab management indeed.

I only use bookmarks to, well bookmark links that I really like a lot, not anything related to “ongoing projects”.

On top of that, browsers can offload the tabs thus making the ram usage minimal, but yeah that would only be useful if you have a ton of stuff opened.
