Difference in homestead exemption between me and my neighbor

First time home buyer here, closed it last year end. Recently I found that my homestead exemption was so large that my property tax was significantly lower than my neighbor's, even if my house has a higher appraised value. Does anybody know why it's the case?

My exemption is " Residential Homestead (Multiple) " while most of my neighbors' are merely "Homestead", if that makes any difference.
