"better" is subjective, IMO.

Time Machine makes it very easy to recover accidentally deleted files  
and roll back changes to files. It is absolutely dead simple to set up  
and use. It's main disadvantages are that it does not produce a  
bootable backup, although it can be used as a total restore. It is  
also difficult to set up with an off/on site rotation of backups.

Carbon Copy Cloner (and the very similar Super Duper) makes it very  
easy to recover form a failed HDD: just boot from your backup. These  
solutions are far less adept at the kind of
'go back three versions of my resume' kind of stuff that Time Machine  
makes so easy. However, CCC makes having rotating sets of backup media  
a snap.

The hard drive manufacturer's are gonna love me for this, but using  
both is truly the ideal solution.

Time Machine for restore-in-place and version access, and CCC for the  
backup backup, a full bootable backup, with multiple sets, one off- 
site at all times. This means a large drive for TM, then multiple  
drives for CCC to populate.

Then there's the 'roll-yer-own' Most of what CCC and TM do, and more,  
can be accomplished with command-line scripts. rsync will let you  
synch changed files to a volume attached locally, to the local file  
server, or to a machine halfway around the world. Proper attention to  
the normally hidden bits of OSX make it simple to create a bootable  
volume.

Beyond this are real tape backup systems and the like, but those are  
for people with terabytes to back up.
