Depending on who usually uses the washer, if it is an elderly then I would suggest getting a top load, it makes it easier for them - need not squat or bend down to pick up the clothes.
Conversely front load washers are usually touted as using less water then top load washers.
However the average time taken to wash with a front load washer is a couple of minutes longer.
If space is a constrain then front load may actually be more beneficial, as one can stack a dryer on top of it.
Ultimately pros and cons for each, depending on what one considers to be a bigger factor when buying.
