I think it really depends on how you want to use it. There are 'Collections' which are basically like custom categories you can create as well as #tags. When you add a bookmark you can put it directly into one of your collections and add tags. I have created a few collections around high level areas but have generally just added bookmarks without sorting, then after I read them I will move them into a bucket. The highlighting feature is very nice as well.
I would try it out for a few days and see how you like it. I definitely think there is something psychologically behind saving links and never reading them, I have quite the backlog.
I have been using https://raindrop.io/ for this and find it quite useful. Never end up reading everything I save but it keeps my browser less chaotic and adding bookmarks from the browser extension and on iOS is seamless.
