I am the author of Crush, I designed Crush for myself: a very happy Unix user for 23 years and someone who can honestly say I love Unix and the Unix philosophy. As such, I feel that I can say with some authority that your first statement is wrong.

The rest of your command is subjective, but I find that being able to see e.g. what user has used a lot of CPU and has many processes running via the command `ps | group ^user cpu={sum ^cpu} proc_count={count}` is both useful and far harder to do in a traditional shell. YMMV.
