Ultimate Spiderman is really happy to be wearing the black suit because it is augmenting his spider powers he doesn’t even need his web shooters to shoot webs. In this universe Peter and Eddie’s father worked on the suit together. The suit used Peter’s Dad’s dna as a starting point which is why Peter feels as if his Dad is with him when he wears the suit. I wish they let Ultimate Spiderman wear the black suiit longer in my opinion he didn’t get to do enough in the black suit and he could’ve done much more with it until it took over. I wish he got to keep it for a week or a month instead of a few hours but they did this in a way that fits into the story at least.
