Agree.
I have a guitar with wild wiring, including, in one switch mode, 3 pickups with series-off-parallel switches.
The parallel combinations are nice for cleans. like you say, but not full enough or enough output for gainier stuff.
For 3 P-Rails, I like the simplicity of 3 position toggles for each one, plus a 5 position pickup selector.
And maybe a separate switch to turn on the neck pickup, to add it to bridge alone or bridge middle.
I like having all 7 combinations available, but not the asymmetry of it, or the awkwardness of dealing with that switch when leaving other positions.
Or, if I want to deal with wiring and using it, a Freeway 10 position instead.
But I'm a little gun-shy of complex wiring plans, after a not great and still unresolved issue with my 3 pickup guitar's wiring that I broke...
