For me it something that I just cringe to see. I realize that in
practice, it is not bad. I just cannot get over feeling uneasy when
seeing things like:

find | grep
cat | grep
ls -l | grep
for i in $(ls -l foo/)
sudo su

I realize that all of it can be used to accomplish a task. So why do I
hate to see it so much?

I understand your issues with all but the last one. A user may need to "sudo
su" due to configuration outside of their control. A system that requires you
to "sudo su" for some task is likely misconfigured, but it is a useful tool to
have around, as a user.

The rest are less useful, and generally imply a limited, incomplete, or flawed
understanding of one or more of the tools you are using.

I no longer configure my machines in a way that it allows a user to gain
full root via sudo. However, when I did, I found "sudo -i" to be more
appropriate than "sudo su" which seems to be more like "su -l". Of
course, you could always do "sudo su -l".

- From the manpage:

- -i The -i (simulate initial login) option runs the shell specified in
the passwd(5) entry of the user that the command is being run as.
The command name argument given to the shell begins with a '-' to
tell the shell to run as a login shell. sudo attempts to change to
that user's home directory before running the shell. It also ini‐
tializes the environment, leaving TERM unchanged, setting HOME,
SHELL, USER, LOGNAME, and PATH, and unsetting all other environment
variables. Note that because the shell to use is determined before
the sudoers file is parsed, a runas_default setting in sudoers will
specify the user to run the shell as but will not affect which
shell is actually run.

You can configure sudo to disallow opening a shell directly with the "-i" and
"-s" options. That is why I indicated that "sudo su" would only be required
with a mis-configured sudo installation. (If policy allows you to run "su"
[or any shell] directly, then the "-s" and "-i" options should be allowed, as
well.)

Nitpick: (sudo su) is roughly equivalent to (sudo -s); (sudo -i) is roughly
equivalent to (sudo su -).
