There is no doubt that provided you can get enough distance away from a large three way for driver integration and still have at least 3 feet behind the listener to any wall then the bigger more dynamic speaker is going to be better!
The only issue with small rooms and big speakers is the bass. Too many big Wilsons, B&W, Focal and countless others have a big bass hump which sounds awful in a small room. Also there is a natural bass boost from the roo below 60HZ - so a 6 db per octave roll off usually is better than flat or boosted bass hump.
