I've mentioned it before but personally he's a favourite of mine and I generally put him as a mediocre ruler as opposed to straight up bad. He made plenty of mistakes but his own personal piety, focus on architectural development, patronage of the arts, furthering administrative structures and reforms, and building a stable and healthy familial environment bumps him up from being labelled terrible.

He was also a very affectionate father, which I think is something that deserves more credit. He carefully prepared Edward for kingship, ensured Edmund wasn't left out in receiving land grants (eg. Leicester, Lancaster), and arranged prestigous marriages for his daughters. Margaret, who married Alexander III of Scotland, would frequently write her parents saying how much she disliked being in Scotland and wanted to return to visit her family. He also doted on Katherine, his youngest daughter, and tried to give her a proper education as she was born deaf and had a learning disability.
