Ok for me I'd want the blackest blacks for sure, I would often use my screen in the pitch black. It's because I live in Spain and in the summer I live with the windows wide open and that means that at night I can't have lights on or my house will be swarming with bugs (the creepy crawly kind, not the regular HN kind :P ) You can use netting etc but in my place this is really difficult.

So yeah that would be super important. Thanks for the comparison!
