Life with the Doctor certainly wouldn't be stable - safe, so long as Harry stayed inside the Tardis, and he would be well cared for, but the only constants in the Doctor's life are his enemies. His companions, his face, and the Tardis itself are ever changing.
This might be a good thing, not because of any souvenirs he might bring to Hogwarts, but because of the mental attitude it would encourage. A stable life may not be the best prepration for the turmoil of Harry's Hogwarts years.
Life with Ranma wouldn't be stable either but I can't really see him staying out of Harry's life post-11 (unlike the Doctor, who hardly ever revisits old companions). Dumbledore may be able to keep Ranma out of Hogwarts, but he's still the kind of loose canon who would tangle up Fate's tapestries, much to her annoyance.
Harry's 11 years with Ranma and Akane could make a great story, of course, and potentially very funny too, but I can't help thinking about what happens after Harry starts Hogwarts.
Pick Belldandy, and the prophecy certainly won't be a problem. As an aspect of Fate herself, she knows how to handle them safely. She's at no risk of the ironic fates so common amongst humans who tamper with the things. But enough of that digression.
If stability were your main criterion, where better than Rivendell, a safe hundred years before the end of the third age. Aragorn makes a pretty good advertisement for the place.
