As per Phil's answer, the idea that a matched system is most efficient from a system level perspective is undeniable. However, at VHF and UHF the receiver noise is well above the noise received by the antenna, so then without doubt less mismatch means better system signal to noise ratio. Also, i imagine that the signal to noise ratio probably changes for ...

Minimizing SWR maximizes power transfer. Better power transfer means more of the noise received by the antenna makes it to your headphones. However, better power transfer does not necessarily improve receive performance, because receive performance depends on the signal to noise ratio. This should follow intuitively from the process of tuning your antenna as ...
