The DC Digital will always look better by virtue of being a digital to digital signal. In addition, it's easier to deal with the handful of games that don't support 480p output. Same goes for the PS1 Digital. Quite frankly, I would always use HDMI mods for mainstream 5th and 6th gen consoles (Saturn, PS1, N64, DC, PS2) and MAYBE even the Xbox. These things existed in a weird time where things were interlaced and field rendering, wacky resolutions and EDTVs were common, and a digital to digital bespoke solution will always beat even the best analog to digital option.
