If all else is equal or approximately equal, I would recommend choosing a program that fully funds you for however long their program is supposed to (typically) take. I'm fortuante to have that deal where I am, and I cannot imagine the stress of trying to find my own funding for the next year or two. A PhD program will put so many demands on you already that trying to find money so you don't live in a box isn't one you need if it can be avoided. Sure, some people get full time jobs to cover living expenses, but that takes so much time away from research, publishing, teaching, and other professional responsibilities that you will need to have if you want to be competitive on the academic job market. If your goal isn't to stay in academia, then perhaps the funding will be less of a concern, but it is a serious thing to take into consideration. Good luck!
