I'm sorry you're having a hard time in your current program. I can't say I know what that's like but I understand the dilemma. I'm not in a program yet but hope to be in one this Fall. I only applied to 2 schools because only 2 felt like a good fit for me, and I didn't want to compromise. I haven't heard back from my 2nd choice, and am 1st on the wait list for my first. I'm pretty sure the 2 who have been offered will not refuse the spots so I'm quite devastated — been moping all week. I can't believe how hard a time I'm having getting over this and honestly fear it'd scarred me for life. My profs have recommended that I cast my net wider next year but I afraid I might settle, and am not sure I want to go through the entire wretched application process again.
I'd agree that a PhD program is about a lot more than academics and rankings. If you're not satisfied with your work, you're going to be burned out before you complete the program. I wonder if it'd be worth it for you to try and transfer. If you have a relationship with a faculty member at your top choice, he/she might be able to help you. I know of people who have done that.
My 2 cents worth.
