The environment thing is mostly about making sure that environment variables that are set by your user and not by root don't leak into root's environment. 99% of the time the leaking variables are harmless, but they can occasionally be the source of some weird and subtle bugs. So typing the extra " -" may save you days or weeks of wrangling on mailing lists/message boards/reddit/whatever. As for sudo being better than su, well, it isn't. It just presents a different set of security and convenience tradeoffs. E.
