For me getting off merry go round is having enough experience to paint decent broad strokes as to what you feel you would want.
Simple things like box counts, aesthetics, matching brands of cables can also play a role into some decisions.
I got into this thinking it was always about SQ and SQ only but sometimes the smaller things that you felt you would not care about comes up in reality.
Example, I prefer to have as little box counts as possible, so if there is a box in my chain, it yielded enough importance to me.
At the end of the day everyone will be different since getting off the merry go round also means that one has to be appreciative and thankful for what they go and at at PEACE with it.
It is human nature to always want the newest shiny toy.
