I use bash as my everyday shell since 1996. I keep on reading the "how great zsh is" articles. And I always try zsh. But after a few minutes/hours, I go back to bash. It's really hard to change.
Just using zsh as a drop-in replacement for bash is pointless. You'd need to discover its features and customize it to get added value.
As a simple example, in bash if you use tab completion and there are multiple options, pressing tab again just reminds you that there are multiple options accompanied by a passive aggressive beep (it used to be this way at least). zsh lets you cycle through the possible completions.

This should fix it in bash:
bind '"\t":menu-complete'
