@Metal TortoiseUltron has tanked blasts from people who can erase planets.
Once he generated a piece of technology that phased an entire galaxy out of existence.
He's liquefied Iron Man's armor with a single blast.
He's had an even fight with Sentry, who is basically Superman.
Defeated Ares and Ms Marvel, who are both roughly on par with Thor.
He's able to transfer his consciousness to another piece of technology and adapt it. (Which would be terribly useful if someone had a piece of technology implanted in them.)
Ultron's secondary powers alone, with his ability to generate new ones, are busted AF.
Yet here we are, with you defending it.
