1.85:1 or open matte to 1.78:1

[Blu-21]

At the risk of this being a insignificant thread/poll, do you prefer a film in its OAR of 1.85:1 with the small black bars in tact on the top and bottom of the screen? or do you find it preferable when studios open up the frame resulting in slightly extra picture information on the top and bottom?

Keep in mind I don't mean when studios crop/over scan the image from 1.85:1 to 1.78:1 which makes for slightly lower resolution and less image visible, and I can understand how opening up the mattes from films in 2.35:1 shot in Super35 to 1.78:1 would turn people off which is why these things aren't what I'm talking about in regards to this poll.
