I have owned a couple of TS2000s in the past and have been hearing this "deaf on VHF/UHF" comment before and don't know where it comes from.  I have used a TS2000 with no problems on the sats, for tropo, and meteor scatter, and it hears just fine on 2m and 70cm with the internal preamp.  The QST review of the radios support this.  It measures the MDS on 2m at 
-141dbm for the TS2000 and -142dbm for the 910H. Not sure that you could hear that 1 DB difference.  There is a bit more difference on FM in favor of the 910H.

Like another person stated, you can catch the end of the AO27 and SO50 pass with the TS2000 when the downlink moves away from the birdie. I also heard that an external mast mounted preamp will put the sats signal above the birdie.

ALso, given the prices for each one, the 910 probably becomes as expensive if not more expensive once you add a CW filter, TXCO, and DSP board, so it is similarly equipped as the TS2000, and the AF DSP in the Icom radios (706, 718, etc) isn't very impressive.

Plus with the TS2000 you get 6m, which makes it a great VHF/UHF weak signal and contesting rig, and as a back up or primary HF rig.  The crossband repeat feature is neat also, where you can work HF or 6m using an HT.
