Everyone has a pref. This is just mine. I have heard good things about the lighthouse, but my prersonal exp has been it's nothing special. UWS (underwater sports) is the largest dive chain in the area. I have heard neg comments on UWS for that reason alone.
But personally I only go to UWS. Doug the manager at the bellevue store is as good as it gets. To the point he has become a good friend, and a dive buddy. When it comes to diving, If he doesn't have it he'll get it. If he doesn't know it, he'll find someone who does.
Bottom line,I trust him to recommend, sell and service my gear.
