There is no conflict.
DVI-I accept broader spectrum. It's compatible with both DVI-D (digtal) and DVI-A (analog, same as VGA) signal.
The difference in picture quality depends on the quality of your video card.
I give you an example from my setup.
My desktop has top notch video card and it uses dual monitors. One is connected through DVI cable, the other one through VGA cable. Both monitors are same brand, same size and almost same model. Honestly, I see no difference in picture quality.
However, when I connect my laptop (average level, average on-board video chip) to one of the monitors through VGA cable, the quality is visibly worse.
