Lancaster by far, it has a million times better reputation and certainly will give you more value for money. Remember, we're paying over 3 grand a year for tuition, I wouldn't spend that money on an ex-poly if I had an offer from a traditional university with a better reputation.
What exactly didn't you like about Lancaster?
The night life is great, there are free bars (pay a tenner and the bar's free), so many nights where it's a pound a drink, the student union is lowly getting better, we have had pendulum, booty love, Dave Pearce came to town, judge jules coming up and we also had ministry of sound.
Lancaster is near Blackpool and Manchester and students go to these places very often, I do that's for sure.
The night life is very good for a city it's size so don't let that hold you back.
