Informal Poll: Do you like them LONG or SHORT?

Oh for heaven's sake... remove your mind from the gutter.
I'm talking about Chapter Length. I'm struggling with this issue in my latest wip and would love some feedback...

I broke the sections into logical places, but now am worried that they're much too long. In terms of word count - they go from 2000 to just over 4000 - which puts some well over 12 pages (and writers: I'm still in Times dbl space -- haven't converted to NY standards yet so you know they'll be longer).

So tell me, readers and writers -- what do you prefer?

A) Long meaty chapters that let you fully escape into the writer's world

B) Short - couple-of-pages-only, so that staying up to read 'just one more chapter' doesn't take you a year

C) a combination of the two because you like the variety, or...

D) I've never paid attention / I just don't care

I appreciate any and all opinions :)
