The mediums allow for different styles of expression. As others have mentioned, a beat-matched set tends to have a bit of a more organic/live feeling to it vs the very rigid mixing of an auto-synched set. If one is better than the other is up to the listener and it's an opinion and not a fact.
Beat matching takes one element out of mixing a set, but does not entirely replace the human element.
The only benefit that comes from the vinyl vs digital debate is giving electronic music message boards a never-ending topic to debate on and keep a steady stream of traffic to the forum
all artists that send demos say "I want it released on vinyl! Vinyl is great!". But when you go and check their sets out, they all play CD's or at best Traktor with vinyl control (which is also becoming more rare every day). It cracks me up every time. I was watching a special about the opening of Space this year, and the last one they interviewed was yapping how he was still a vinyl junkie and vinyl was great and he was still oldskool etc etc etc. Next you see is him playing at Space, and there's not a turntable in the booth to be found.
