QMUL vs York insurance choice for chemistry

This is going to be a long(-ish?) post as I’m really trying to figure this out.
For context:
• I’m in Year 13 trying to decide on an insurance uni for chemistry (with industrial placement year)
• I live in London
• I want to be educated well at uni, but I’m really looking for personal growth
• I’m interested in becoming a toxicologist (but if it doesn’t work out, I wouldn’t mind working in other sectors..)
• I tend to get bored of places easily, so I hope to travel in the future (a bit more than the average person anyway)
• (I’ve firmed Manchester if you think that’s relevant)
I have to choose between QMUL and York. York seems to have better teaching quality and I prefer the course, but I’m unsure about the city and social life there. I’ve heard that rent is expensive in York, and I don’t want to struggle after Y1 if I no longer live in uni accommodation.
QMUL is a commutable distance so I don’t need to worry about accommodation costs. But a reason I’m hesitant to go there is that some people I know are going, which might sound silly but I’d prefer to be somewhere new with people I don’t know.
This is a plus for York I guess? But as I mentioned above, I tend to get bored of places easily, and am afraid I’ll get bored of York since it’s a small city. York also doesn’t seem to be the most diverse; I’m worried this might impact me in impractical ways (e.g. finding hairstylists, products, cultural foods..)
Could anyone shed some light on my situation? There are other things I’ve considered too, but I’m still unsure and don’t want to ramble for too long. Thank you in advance!
