I should imagine you'll get as may votes for one as t'other.
POR has 5 pools, good theming, boat hire, cycle hire, a nice bar lounge and a full service restaurant. But it's after POFQ on the bus route so the bus is frequently full, and as it has twice as many rooms as POFQ its Food Court can be very busy.
POFQ has 1 pool, but is much more compact. But it has no full service restaurant, and doesn't really have a proper bar lounge. Of course, you can always walk to Riverside if you want those things (or get the boat).
