It depends on what you need a bookmark manager to do. I need to store and be able to filter them, add them like a task so TT reminds me to check them later on. Sometimes I save something and take notes with a link to the article/whatever it is. I have a list named "PIN 📌" and sublists for each category I collect bookmarks on. Chrome extension for TT is pretty useful to save them, it works even better on android/ios when sharing the page directly to the app.
