I've applied for electronic engineering at Surrey, among others, although not Southampton, and physics rather than ee at Manchester. But I would say that from the league tables I've seen, after Surrey Southampton ranks highest. That said, since Manchester is such a large uni, there will almost always be the opportunity to work on some fairly unique project or research because chances are there will be a professor interested in it. On the whole, any department in the top 15 is a very good place to study, and it comes down to how much you like the look of the university and local area. I haven't been to Southampton so I can't compare, but I had an interview for physics at Manchester the other day and the university on the whole is really nice, if you are OK with living in a big city then it has a lot to offer. I also saw the electronic and electrical engineering at Manchester at the open day and really liked the attitude, the staff, the research they were doing. Personally I preferred Surrey because of the space technology there, and so didn't apply to Manchester for ee. But they're all great really, go with your personal likes and dislikes.
