Beyond this, I do think going to a university that is locally respected can help you get employment (or so I have been told by some current teachers, anyway).
However, a PGCE is a fairly standardised qualification and it doesn't really matter where you do it too much- I think it's best to pick a uni in a suitable location (you can be asked to commute a long way to placement at some universities) and one you get a good, supportive vibe from.
You get to apply to three choices initially, and personally, I found you could tell a lot about the universities at interview. I chose the one that felt most supportive and the only one where they seemed keen we had a life beyond the PGCE. It is going to be a tough year, so I think a supportive, organised uni is a must!
Hope this helps a bit!
