If you want to get technical... it matters more if they were mixed and/or mastered digitally than recorded digitally when it comes to vinyl.
If they were recorded analogue but mixed and mastered (or just mastered) digitally they've already gone through the digital conversion process (and actually you're probably adding more noise to the signal from the extra digital to analogue conversion to put it on the vinyl).
If it was recorded and/or mixed digitally but mastered onto analogue tape and tape is used as the vinyl source, vinyl could be better. Some engineers even though it was recorded and mix digitally still like to master on tape though not near as common as the old days.
Actually though, sampling rate can come into play as well with vinyl. If it was digitally recorded/mixed in higher resolution than CD and used the pre-sample rate converted master as the source for the vinyl it would probably sound better.
Then again if the people making the vinyl suck or the equpiment is poor or not maintained or properly biased and aligned that can also detract from quality. Lots of variables with analogue unlike the digital domain which can be bit perfect...
That said, I still buy modern vinyl of the albums I really enjoy and have a decent listening setup. I just like the whole touchy feely hands on aspect and watching it spin, plus the giant artwork is cool. Some bands still only release their stuff on vinyl that I listen to as well.
And it's really sad that DVD Audio and SACD have been around for 7 years and haven't really taken off. They need to just kill the CD already.
