How old is your kid?
Here is just my feeling.
If your kid is toddler, choose the play house learning center.
If your kid is JK or SK, choose the Manotick Montessori.
If your kid is very quite, choose the play house learning center.
if your kid is very active, choose the Manotick Montessori. (Montessori has no circle time. Children usually be quite do some work.)
