I think each one has its own pros and cons.
Sometimes i might like the 'maze' type ones where it actually takes some effort to find and kill a person.
However, i also like plain and simple DD especially if theres a barrel and everyones really close, KABOOM! . But then again, some really tight DD can totally suck cos you end up getting raped from all angles and cant move anywhere.
Well thats my 2 cents
