London exchange schools

Hi,

I have the possibility to go on exchange next year and really want to go to London. However, my school only has deals with Regent´s and Westminster. They also have deals with schools like SSE, HEC, Nova, St. Gallen, and Bocconi to name a few. I guess my question is how decent are the two London schools? I know that they aren´t LSE, LBS and Imperial quality. As it´s only 4 months exchange it might not matter at much as my MSc is from a good school. Anyone got any ideas or thoughts whether those schools are decent enough to choose or should I instead go to Bocconi even if i really want London. How do future employees look at exchange schools if I have good grades and several relevant internships?

Thanks
