Receiving is mainly a matter of peaking S/N, and selecting a good 
antenna under this aspect is desiderable.
Transmitting is instead the matter of maximizing the antenna efficiency 
or the gain if any.
A screwdriver antenna i.e. 0.001% efficient can work as a receiving 
aerial but it's quite difficult to be answered transmitting with it.
When reciprocity doesn't occurr, there is certainly a lack of S/N in one 
of the two sides but this isn't enough to deduct if rx side is really 
the main and only weak ring of the chain.
The statement that the "guilty" is the guy at the RX side stops to be
true when the transmitted signal is so weak to be under most of the 
receivers ground floor (here intended as band noise or blocking state 
and not as white noise) and average antennas features.
Definitely, is very possible that in largely populated areas average 
stations are unable to erect stackings of beverages or any other aerial 
able to reject high angles or unwanted directions. In such case, it's 
hard to be able to detect relatively weak signals if out of the "topic" 
moments. (less QRM is typically at receiving sunrise)
On the other hand, far from those high qrm areas any antenna has 
inherently a better receiving performance, but to hear "so well"
is far to be an insurance to be heard and a reason to assign always the 
fault to other side.
The good operator (I hate this limitative expression) should know what's 
going to front, including that not everything heard is workable, and 
that ears are nearly nothing without having first arranged (or tried to 
arrange) a station that's balanced between RX and TX features.
