It really just depends on your personal taste. Both have great exclusives. If you're into story driven Singleplayer Games, Infamous is for you. You like racing? Don't get that PS4 until next year, no racing game whatsoever (nobody wants Need for Speed, seriously). There's also no strategy stuff such as Zoo Tycoon. But you get awesome Indie stuff like Outlast and Resogun and also for free with PS Plus.
No one can be calle absolutely better than the other. Just look for yourself which games you like more. But to be quite hones, at this early stage, you should just wait if you are still not sure which one to get. Who knows what games might come in the future. I say at least wait for E3. I think there will be shitloads of announcements for both consoles.
