My umpteenth yrs of using top loading wm tell me it's the best for you. Not the Jap types but the Euro or American ones, where the rotating druim is vertical. Jap horiz rotating barrels use more water and more $$$.
Other Reasons:
1. more economical with water use
2. can always open the cover and put in last min items (front loading will cause S'pore to flood if you open after water has filled, but not top loaders)
3. tend to be narrower but taller so use up less space - also you dont need to leave space for door opening or to squat in front; yr butt takes up space in case u dun realise it.
