Well, UC is a better value; expect to get a much longer playtime with it than with both HOTDs combined. The graphics and overall production values are higher, and in all it's really really awesome. However, I wouldn't recommend it as a starting point for those new to RE; if possible, try getting RE4 for Wii first (it's cheaper than either game) and then Umbrella Chronicles (not for storyline reasons, but because it just seems to flow better that way). If you can get all three of them really cheap, that'd obviously be the best route.
