Since this was your first time at both places, you can be forgiven to think that they are the same each and every day. They are not!
The food varies quite a bit in each place. Sometimes it is better in Oase, and sometimes in FKKW. Also, on summer days each place has a bbq going in the early evening. What is alwasy different between FKKW and Oase in the food department is this: at FKKW there is something to eat set out all day, whereas this is generally not the case at Oase.
Drinks: both places serve you as much non-alcoholic drink as you can handle. At FKKW that also include non-alcoholic beer. Plus, at FKKW you can now buy beer and mixed drinks as well.
Girls: I have seen plenty of gorgeous model-type bodies at FKKW. Beating Irina or Olga or Vanessa or Betty (all at FKKW) in the gorgeous body competiton is very hard. But like I said, who is on shift is different from day to day.
Public sex: there is plenty to be had at Oase. Almost always in the kino. In particular when there is a waiting list for rooms, most girls will go for the hump in the kino. (And the same is true at FKKW and Palace).
Any any case, I agree wiht your general assessment: you can't go wrong in either place.
