Hmmm! Looking at it now... Wait: your definition of fibo-gen2 is not exactly equivalent to the others in terms of work when verbose is off.
Good spot! It's consistent now. Generators and delay/force are roughly the same speed (although the latter explodes in terms of garbage collection), whereas the "ugly" solution outperforms them all (2.5 times faster).
