I also bought the Armory set with Alfred because of a deal (the days of 50% off coupon codes), but I sold the whole thing shortly afterwards. The suit from TDK/TDKR is arguably the iconic Nolan batsuit, so I bought it thinking it would be a good Batman figure to represent the Nolan films. In the end, I just didn't connect with the figure, mainly because I didn't have a strong connection to the character or design (though I love Christian Bale in the role). Right now, I only have a Selina Kyle figure, though I'm considering getting Two Face or a Bat-pod next. It feels a little odd not having a Batman from movies I really loved, but I'd rather have figures of the side characters that mean the most to me.
So my only word of advice is to make sure you're buying a Batman figure because it's something you really want rather than because it represents movies you really enjoy. If that's not part of your decision-making process though, get the Armory version (and maybe an unmasked Bruce Wayne head too).
