Dr. Strange did better by Peter than Tony
This is interesting. We all know how toxic IronDad is, and this theory suggests that Dr. Strange did a better job as a mentor because he actually listened to Peter and cared about what happened to him. And they had conflicts because they were both equally engaged in the situation--Dr. Strange wasn't hiding information from Peter or talking down to him. So pretty much the opposite of the way Tony treated Peter.
Note: I haven't seen No Way Home.

Peter was still getting used to how quiet his new life was--without MJ, Ned...or Aunt May.
He was the only one who remembered now.
It felt as though he'd grown up, like now he was finally an adult.
Part of it was all the losses, but another part was because of Dr. Strange.
Dr. Strange had talked to Peter like he MATTERED. And sure, they disagreed. But Dr. Strange didn't make fun of Peter or treat him like a know-nothing kid.
And Dr. Strange didn't want anything FROM Peter. He was willing to consider doing something FOR Peter without needing anything in return.
When Peter thought about that, it made him realize just how awful Mr. Stark had been to Peter. Mr. Stark had given Peter a suit IF Peter did what he wanted. And when Peter said No, Mr. Stark had threatened to tell Aunt May.
And Mr. Stark had NOT treated Peter well. Ghosting Peter, telling him to "zip it"...Peter realized now that he should have walked away from Mr. Stark at the start.
Maybe if Peter had, he would have had the chance to meet someone he could REALLY look up to. Maybe even Dr. Strange.
Probably not--their powers were too different--but at least now Peter knew the difference between a mentor and a user.
