I just bought a Tivo Premiere last month while they had an OTA only special sale. This may be apples and oranges but I'll share my experience with the Tivo tuners and my Sony 46EX620.
Like you, I wanted to know if there was a difference in tuner sensitivity so I connected both to the antenna allowing quick comparisons by changing input settings. When my weakest channel was on the edge of dropping out, I switched back and forth, over an over and saw no significant difference. If one was pixellating the other was also. On a very rare occasion when the signal was low but very steady, the Sony did tend to drop out a little less but it was still what I would consider to be "unwatchable". If the SNR is swinging near or below 15dB, it's going to pixelate and drop out no matter what tuner is being used.
FWIW, I'm using a mast mounted preamp which according to what I've read, affects the ATSC tuner's noise figure in a positive way. I don't know how each of these tuners might perform without the preamp.
