Your room is way too small for almost all of these speakers. The Personas 9H might work due to the room correction of the speaker and their ability to tune out bass nodes and standing waves.
The Persona 3F are similar the 9H, in many ways, the 9H do indeed sound better, the biggest issue with the Personas is setup many dealers are not up to the task of showcasing a speaker system with this kind of resolution.
As per the Focals sounding bright they are a bright speaker it is only with setup that speakers with high resolution tweeters Personas, Focals, etc will sound good, the Dynaudios are a much more laid back sound without the incredible clarity that the Focals or Personas have so they are much less likely to overwelm a listener with too much treble information.
The Wilson Sashas are a bit over blown in the bass and will probably sound very boomy in that size room.
What you need is either a smaller reference speaker that won't overload the room or some kind of room tuning either in the speaker or external.
