There are endless possibilities in Vivaldi to reach bookmarks.
Apart from the bookmarks bar:
Speed Dial
File menu
Ctrl+B
Bookmark panel
Quick commands (F2)
You can configure the quick command so it show bookmarks first, if you know the name or parts of the name it is really quick.

Just play a bit with all possibilities Vivaldi have, change from one software to another need sometimes to change your workflow.
But it's also great to try something different sometimes.
