Help choosing university for BSc Computer Science (G400)?

Hey guys,

I'm an international student who's gotten admission to the following universities for undergraduate studies in Computer Science.

(i) University College London
(ii) University of Warwick
(iii) University of Manchester
(iv) King's College London

Although I have gained admission to these universities, I'm not quite sure which one to choose as my first and second preference(s). I have checked various ranking lists but they seem to be quite inconsistent. Which university will give me a strong learning experience, whilst also boosting my career prospects?
Personally I'm tilted towards UCL and Warwick, but I'm open to suggestions.
