Comparison of For/While Loop

Hey all,

My roomate is absurdly stubborn and refuses, on 'principle,'  to ever
use a While Loop for basic Computer Science programs. Instead he opts
for a For Loop.

I was wondering if anybody new of any comparisons between For and
While loops (efficiency, etc.). From my perspective, While loops are
less to write and conceptially easier to read - but I wasn't sure if
there were legitimate reasons for using either.

Thanks!
