John, never had Iletas, but in my experience Red Devil or Midas can give Festae run for the money, the way Iletas looks (Amphilophus species anyway), it remind me the striped Midas, I had years back, he was no joke.
Also other Red Devil I had with Festae, lost throne to Festae, only because Red Terror overgrow him considerably, but boy that was a longest cichlids fight I ever saw, had to separate them, too much respect for the Devil to just waste him like that. He still alive by the way, 9 years after.
Here the pictures of them almost 10 y ago:
