Watch Them Feed rules, as does RTR. In fact, I am of the apparently-minority opinion that each and every In Flames album rawks in its own particular way, and as such, it's kinda pointless to cross-compare them, to say, for instance, "RTR should be more like Whoracle" when it is clear that they are no longer musically (that is, with respect to inspiration) capable of going back to that sound, nor, clearly, are they desiring to do this.
I think we'd all enjoy life a lot more if we abandoned some of our pretensions and allowed ourselves to appreciate songs like Watch Them Feed and albums like RTR regardless of whatever Olympian standards we have for what an In Flames song or album should sound like. And if current In Flames just isn't your type of music, that's cool as well, but you can't really blame In Flames for that.
