If you want to be a radiology technician it really doesn't matter whether you go to a university, a technical school, or a hospital program. What matters is that you have your accredidation.
Personally I would recommend hospital programs. I personally believe they give you better training for less moey. Having a degree doesn't make you any more money as a tech, it does however open more doors to you down the line if you want to get into management or teaching.
You can always go back and get your degree after working as a tech and if you're lucky you may even be able to get your employer to pay for it.
