UEL is a magnificent university to study at. The Times University Guide ranking system favours the older universities... Maybe UEL does have less reputation, if any, but you can still have a great chance for employment if you end up with a first honours degree - with the lower facilities and teaching quality, if you do manage with a first honours degree, it speaks volume of your learning abilities whereas others can get a 2:2 degree from a top 10 university.
The main reason people are insulting UEL is because of the rank in The Times. They have not studied at this university. If you choose this university you will need to be prepared to want to study hard because the lecturers are "easy going" and wants to make you feel relaxed. Motivation and encouragement from others in this university is less but you can succeed.
UEL is a new university, not a failing university. If you choose a university solely because of the league table then you are one of those who have not researched the university as a whole, the department, and the course you want to study. And if you are this person, you are likely to fail no matter which university you pick. In the end, you are the one looking for employment, not the university.
If it makes you feel any better, UEL is not at the bottom of the league table anymore. It has risen by quite a bit in rank. 93/109 excluding London Metropolitan University.
Read the QAA report on UEL and you'll see that this new university has been given a "broad confidence" meaning it has the potential to rise up in the league table in the future; kind of like investing - you do not pick which shares to buy because a lot of others tell you to buy that one, or it appears to be profitable out of face value. Instead, you buy shares based on proper research.
If you have any actual proof that UEL is bad, such as past experience, then feel free to say so. Words such as "hahaha" and "Do not go, trust me" are obviously immature kids who categorises a university as good or bad from the league table.
