Common App Personal Essay

I’m in the process of working on my personal essay for transfer apps through the Common App, and I’m a bit torn on how I should be writing the essay. Much of what I’ve read says that the essay should be specialized to each school I’m applying to, but many of the schools I’m applying to have a similar “Why us” essay on their supplement, which would seem a bit reduntant to me if I wrote about the specific school twice. Any thoughts on whether or not it is better to specifically address the institution twice or do a general essay and specific essay for the supplement?
