What tool could I use to compare crop type changes between two shapefiles of agricultural fields for the same area but different years (and not exactly the same acreage)?

Both shapefiles have over 14,000 rows in their attribute tables, with 150 different types of crops which I have recategorized using Python into 12 categories.  I can look at the maps side by side and see changes, but if I want to know what the acreage of a crop in the second map replaced in the first map, it seems there should be a way to do that.  I tried "Table Compare" in the Data Comparison toolbox, but it didn't like that the number of rows in the two tables are not exactly the same.  Any suggestions?
