Given limited time and , of course, cash, I am trying to prioritize my punting plans for an upcoming trip to HK.
Honey girls seem to be marketed as being more attractive then walkups however, there seems to be a great variance in service quality along with the possibility of B&S as well as the high amount of photoshopping on the pics along with the higher cost.  There also seems to be a lack of spur of the moment availability. On the plus side, if one is specifically seeking a particular type such as the Chinese Spinners ST seems to have or the Thai ladies of TR, that seems to be a plus.
  Walkups seem to have the advantage of being able to see what you're buying before committing as well as a lower price point but seem to be the luck of the draw as for service quality.  Also, not knowing what will be available as you walk the halls .  
Named saunas seem to have consistent quality but older providers.  At least a few such as K Pressure offer you some choice.  
  What are your preferences and why ?  What would you say your experience as been as far as satisfaction with the different options available ?

in every category you mentioned it's always the luck of the drawer … in fact where women are concerned what service you get depends on her mood at moment, the chemistry that can be developed during the short span of time with her, her mood, and most importantly her mood !
even if you go to one of the girls that had great reviews here doesn't guarantee that you will get great service although chances are it'll be higher
for hotel girls and walk ups you have very limited time with the girl so if your first time was decent the do a repeat as her service usually would be better if she remembers you (and that you tipped her the last time)
