QMUL or City St George's?

I know this is a complete mid off but I see alot of people comparing the two universities. One is better ranked nationally and isn't a Russel group whilst one is better ranked globally, is a Russel group but is also a meme uni in a shitty area. What's the verdict? Bearing in mind QMUL used to blow city out the water interms of rankings years back but now... the tables have turned
