the UV5R is not the GT3.
And yeah, you can hear the difference, especially when mobile inside a 
vehicle.
The selectivity may not be anywhere near as good on the GT3, but that is 
kind of a moot point when talking about FM and using repeaters most of the 
time.  The TH F6A is just as susseptible to noise and intermod and crap as 
the GT3, and quite often the gt3 is less susseptible when the two are side 
by side using the same kind of antenna etc.
I use both the th F6A and the GT3 daily in a high RF noise environment and I 
can say the GT3 performs better most of the time on UHF at least on 
receive...it has a lower audio amplifier noise floor as well which helps. 
Like I said, I like my th F6A, but direct comparisons over a couple years of 
fairly heavy daily use on both nearby and more distant repeaters has shown, 
at least to me, that the receiver is comparatively better in the gt3 
compared to the TH F6A and even compared to the UV5R.
Just my observations which could very well be subjective in nature.

I doubt if you can hear the difference in .06 of a microvolt.  The big
difference is selectivity, not nearly as good on uv5, for example.  The
uv5, for example, is a software designed radio, which is not the same at
all when comparing receivers.
