I use both 5362 and 8300.
Two 5362's in wall and 8300's in my power conditioners.
They were all manufactured 20+ years ago.
When trying them in wall the 5362 was slightly richer sounding with the 8300 sounding a little lighter/brighter.
I use the 8300's in my power conditioners which are fed by the 5362.
I purchased a bunch (24 I think) of the 8300's as used pulls for $30/shipped which is partly why I went with them.
Back then the 5362 retailed for <$20, but you could find them for <$8 at electrical supply houses.
There were also different versions of the 8300 with some being plated brass and some being plain brass (some of those in my bulk purchase were plated).
I used the plain version for HiFi.
I'll add that in my city using 20 amp units in a 15 amp system is against code.
