What do you prefer the most vertical nav bar or horizontal nav bar explain your answer?

It is recommended to use vertical navigation when your application requires global navigation that is displayed on the left. While vertical navigation menus generally consume more space than their horizontal counterparts, they have become more popular as desktop monitors move to wide-screen formats.

What is a disadvantage of vertical navigation?

The main drawback to using vertical navigation compared to horizontal navigation is that it takes up more space and, as a result, there is less room available for content. Vertical navigation usually results in pages with a lower content-to-chrome ratio than horizontal navigation.
