The "best" version of "ping"?

Throughout the years, I've seen a number of different versions of "ping" with various features like: - "-f" switch which pings a destination as fast as possible - "-c" switch which acts like the ping function on a cisco router - TTL reporting - improved clock resolution - ability to specify data pattern - ability to source jumbograms I would be interested in finding versions of "ping" with such "enhanced" functionality. Does anyone have either a canonical "best" version that incorporates many/all of these enhancements or, failing that, pointers to various versions which incorporate different sets of features?
