Go to UCL - you sound like you'd be happier there. I've used the EEE computer room before and well, let's just say it ain't pretty. Imperial EEE is a phenomenal course, and I've got massive respect for anyone who attempts it, let alone gets through it, but it's ridiculously, ridiculously hard - often thought of as Imperial's hardest course (along with JMC), and you'll be worked like a dog.
Lot's of people here saying Imperial will guarantee you a job are plain wrong. Imperial is perhaps better respected in the engineering industry than UCL, but at the end of the day it only gets you an interview.
