I would'nt say its better, its suited to a different use case.

* It can pause a process based on load, cgroups cannot do this 
(something the proprietary tool cpuwatch does)

* It runs anywhere that it can access /proc/$pid of the process its 
operating on and has no other requirements apart from this (similar to 
the cpulimit tool already in Debian, except cputool operates on process 
groups and also supports load monitoring, it also has an optimized 
design allowing it to operate on thousands of processes)
