华威吧，直观感觉！

Sorry mate I cannot type Chinese at the moment, but I am sure you can read some English. All the Universities you have listed above are, at least for the most of the time, ranked in the UK top 10, so generally speaking they are all good and don't have very big differences. In terms of the business schools, I don't know other Universities, but WBS (Warwick Business School) is definitely a good one. I don't know if you want to pursue a Ph.D. study afterwards, if you do, my suggestion is having a look at the ref (research excellent framework) ranking outcomes, the 2014 ref ranking will be published on 18 Dec 2014.  I hope these help.

thank you for sharing your idea. it is very useful
