Any sysadmin (or devops engineer) worth trusting with root on production machines a) knows how to convert from one to the other b) knows there isn't a difference between the two unless you actually go look at the script in between the wget and the execution (and, probably, go look at what it downloads too and read through all the code). On non-production machines the first one is easier.
