Good question requiring a good answer, however, I'm going to try and answer anyway!
What you need is a good result from your studies - not a mediocre result from a good college!
Don't get sucked into college snobbery - I don't believe people in the industry will require that. If they do? personally I'd ignore them!
If you are happy with your present surroundings why change? It can only add hassle to your studies and may effect your results. (Human Factors stuff - I believe!)
On the other hand, if you find you do not fit in well with your present surroundings and feel you may benefit from a move, go and do it. But mind what you wish for - you might get it!
I suppose what I'm saying is - do it from your personal perspective - not because of League Tables!
Hope this helps
