Fuji stuff again

Can't say thanks enough for all the info on the Fuji gsw690's.My last source of confusion concerns the rangefinders.
Apparently they changed significantly from the 11 to the 111.Yet I can't find a consensus about the advantages of
the "brighter"one on the 111 vs the" contrasty "one on the 11.What circumstances makes one better than the other?
Does one improve focusing accuracy in certain conditions?
Thanks in advance for any assistance,Peter
