There is no easy route into the legal profession. No cunning plan, and no amount of blaggery or stuntery will land you a pupillage or a training contract.
Study the degree subject which most interests you. Study at the most competitive university which offers you a place.
University rankings don't matter. They are made up by lazy journalists, and are ignored by law firms and sets of chambers. The rankings are of interest only to ill-informed students, their ill-informed parents, and lazy journalists.
The quality of your higher education does matter. In general, more resources mean better education. That's why it's worth trying for big name universities.
Only study law if the subject interests you. Do not try to become a lawyer because you like the idea of money or think that "Suits" is real life. Think about what you want to do and why you want to do it.
Good luck!
