I'm from Leeds and love Leeds as a city, currently living in Sheffield (studying at SHU) and it's nice here, very hilly though and the nightlife isn't that bad, in my opinion the best nights out are Wednesday,Thursday and Friday. I have friends here that are from Leicester and they said the nightlife isn't that good there. I can't comment on Leeds nightlife because I live so far away from the city that it's too expensive to get a taxi but I know people who love it.
