Really the legend to me aren`t anyone in techno.
I got into techno via Industrial, throbbing gristle, kraftwerk, kodeIV, Swans, Voltair etc, and they come from the Sturm and Drang origination of electronica, rather than atkins etc, who come from the house origins.
So I would say personally, Atkins and Aphex, have no effect on me whatsoever, so are NOT legends to me.
This whole topic is subjective, their is no answer any more valid than any other.
The real legends are people like Bob Moog and co, for inventing the early and crazy synthesisers and drum machines.
Ahhhh good old compurhythm.
