I saw both ends of the Branchy spectrum
In the early 70's we had a Sqn Ldr Eng at Cottesnore who was a miserable old git and I think almost universally disliked.
In the late 70's at RAF Brandy we had a younger Sqn Ldr Eng who was excellent and universally liked and respected for his manner and knowledge.
Both I believe were ex Brats.
One of my oldest RAF friends (also ex Brat) ended up as a Branchy Engo but unfortunately turned out to be a lying,cheating extremely untrustworthy character (but that is another story).
So yes - very much depends on the individual concerned.
