To extend the mix or not?

So what do you like for your trance mixes?

A song-to-song extended mix over 3mins?

or

the quick 1 min bass changes?

Discuss.

I find the quick bass changes sound cleaner but boring.

The long mixes are more interesting but can get messy with extra bars and too many layers...

if it sounds shit, don't do it.

Mostly depends on the format of the tracks.
