Why is it better to use “#!/usr/bin/env NAME†instead of “#!/path/to/NAME†as my shebang?

I already stumbled over #!/usr/bin/env bash on numerous occasions and never questioned it. Now, I'm wondering what the purpose of wrapping the shell interpreter in an env command, i.e. why not just write #!/bin/bash, #!/bin/sh or whatever?

I think this became popular because of python.
With this you can do
#!/usr/bin/env python3
for example and be quite sure env will find the right version and location for the executable.
Then this migrated to other shells because it seems like a good practice to always do even if you know where that particular shell is.
