I may be looking back with nostalgia clouding my judgement but I'm sure the Amiga CLI was much more capable than DOS. I remember my first year in university, discovering Linux & Solaris and thinking "wow, it's like a multiuser Amiga" (my comparision being the power of the shell). It was certainly my familiarity with the Amiga CLI that gave me the confidence to dive into Linux. My other friends (all with DOS/Windows experience) seemed to fear csh/tcsh/bash.
