Metacritic:
Mass Effect - 91 (89 for PC)
The Witcher - 81 (86 for enhanced edition)
Kings Bounty - 80
Awards wise, I tend to think that Mass Effect winning IGN's Best RPG of the Year, Best Score, Best Story; New York Times Best Game of the Year; SpikeTV, TeamXbox, GameTrailers and X-Play's Best RPG of 2007 trumps The Witchers PC awards.
Mass Effect won far more categories outside of just it's console's awards. ME won RPG of the year on 5 sites. The Witcher did not. So don't call the Witcher better from ANY critical standpoint, when it is not. The Witcher did get more awards, but the majority of them were from PC gaming magazines, and not general magazines that pitted the Witcher against more titles (unlike ME, which won against every other game in 2007). Even King's Bounty won tons of PC awards, despite it having an average MC rating of 80 (great game, BTW).
Back from the dead, I'm afraid.
