Cron Job to Warm Cache

First of all is there a reason to use your ee cron command instead of creating a cron job normally, I’m not clear on what the difference is?

I want to create a cron job that loads a webpage, would I just use the standard format something like this?
wget -O - >/dev/null 2>&1

So would this be correct?
ee cron create --command=‘wget -O - >/dev/null 2>&1’ --schedule=’@every 10m’
