What value does del.icio.us have over other ‘bookmarking’ options (other than ‘social bookmarking’)?

Question From User - Answers in Comments.

If one is not concerned about distributing ones bookmarks to others, but only wants to be able to quickly create them on-the-fly (and organize them then or later), what particular value, if any, does del.icio.us have over other common bookmarking options -- Yahoo! Bookmarks, Google Bookmarks, etc. ?

Thanks.
