This is actually a poll against q3 mappers from a n00b.
Do you test your lighting with r_overbrightbits 0?
And which do you prefer or consider as primary mode, 0 or 1?
If you use unix, how do you test with 1?
Any answer, such as just "No, only 1." would be appreciated.

I test with both. If shaders look different in each mode, I'll mess with the rgbgens in the shader to try and get them to look similar in both modes.

Edit: Get to know each of the rgbgen parameters, which ones depend on overbrightbits and when they are used as default, when no rgbgen is specified.

As for default rgbGen, IIRC, "blendFunc add" is "rgbGen identitylighting" though some default shaders specify rgbGen identity even if they are additive blending which I think odd.
And "blendFunc filter" is "rgbGen identity".
Oh, "blendFunc blend" is identitylighting though I never know why they are and the cases of other blending such as "blendFunc GL_DST_COLOR GL_SRC_COLOR" and other uncommon combinations.
