zahavasdad is correct in that comparisons would be unfair. There are huge administrative economies of scale and one reason property taxes are low in NYC (at least for owner-occupied residential property) are that the per pupil expenditures here are much lower than in small inefficient suburban districts. But people in NY and NJ prefer to continue paying taxes that are so high as to be nearly confiscatory than to consolidate school districts.
