With all this hostility going back and forth, they danced around the key point but never actually addressed it: what specialty is this? If it's a competitive specialty in which 1-3 aways are standard, you still need to do them, and you won't match without them. Most top programs match 1-2 home students a year, but everyone goes through the same song and dance.
Also, you never know what you're going to find. My home program in med school was elite, but when I went on my aways I realized that it was really unlike most other programs around the country, and in the end it wasn't the kind of program I wanted for myself. If I had never gone away I would have been happy to stay, but it wouldn't have been the best fit for me. And this is something you can't know until you spend a month at another institution, no matter how well you know your home program.
Edit: also want to add that maybe your home program doesn't like you as much as you hope they do. there were plenty of superstar med students at my school who rubbed the residents the wrong way, and there's no recovering from that, even at your home program.
