Since this appears to be primarily TV/Cinema...
I'd assume that you're going to use subwoofers to enhance the cinema experience. If that is the case, the HK 990 would be an easy call IMO. As mentioned above, it features an excellent power amp section, but that wouldn't be my major focus here. Unless the other units offer the same type of bass management/room correction software, I'd be pretty confident that the HK gives you easier/better subwoofer integration than any of the other choices. If any of the others is similarly equipped, then it might deserve consideration as well, but - in any case - the subwoofer integration capabilities would be my main focus in an integrated amp search for this application.
