Should I use HDMI or compoments with my analog CRT?

[Headphone Czar]

I heard analog should stick with analog to prevent the Analog to digital conversion, which can add artifacts to the picture. In my Samsung manual, they really praise the digital connection as the best connection possible for the TV (DVI). I tried both, & I believe the HDMI is a bit sharper.. But Before I did the comparison I thought the HDMI connecton would look better.. Maybe the Plecebo effect..
