Um Ultron is nothing compared to the King of Technopaths in either Marvel or DC Hank Henshaw, the individual who can oneshot Supes, enter the Source Wall and learn its secrets, and take over and control ANY technology of any kind. The range of tech he's assimilated is wide, Kryptonian, New-God, Oan tech, tech I don't think Ultron can even touch. I'm sorry but there's nobody in Marvel who's quite like the Cyborg Superman who does not have a human mind, his mind is a hybrid of a kryptonian mind and a computer, with absolute recall and memory which grants him the ability to recreate a form he's assumed using other tech from just memory alone, like Apokoliptian tech from H/P. Anyone who argues against Hank Henshaw when he's pitted up against another machine is just asking for spite beyond spite!
