Top floor
1. doesn't need to worry about above toilet leaking which sometimes can be problematic if upstair owner doesn't cooperate.
2. doesn't need to bear chair dragging sound, jumping up and down sound.
3. Less noise

Water pressure is not a problem because most mid and high tier condo has booster pump for top floor supply.
If building management is good, roof leaking needless to worry, because it is building management responsible.
Most of the time, the top floor unit is never the most top floor. The most top floor is the floor with water tank and elevator installation floor, and most high tier condo cover the floor with roof top.
So no direct sunlight on top floor cement in this situation, unlike those low cost flat.

Both have pro and cons but when mostly issues considered, generally top floor > low floor.
