You asked about red production breeds.  We have had several RSLs, all have had or still have health issues, save one.  In terms of temperament, they are friendly and docile, nice to others, just charming personalities.  We know others who have had great luck with RSLs so it is just the luck of the draw.  We have a new Cinnamon Queen pullet, too young to lay yet so the jury is still out on her.  She is a RIR / RIW hybrid and as has already been mentioned RIRs tend to be mean to flock mates.  She is a bit timid and prefers to be by herself.  Thus far, no health issues, so fingers crossed. 
We have three Orpingtons, one is highly food aggressive, the other is a bit of a bully and one is afraid of her shadow. 
We've also had EEs, good layers but also health issues. 
The Australorps we experienced are calm, quiet and have sweet personalities.
Every bird is an individual with distinct personality quirks, no matter the breed or mixture.  The point is eggs, right?  Get what you want for the yield you desire and the rest will work itself out.
