The difference, by ear
Crossover came from the same clubs and the same bills, and kept hardcore's brevity. The tell is song length.
Both are shouted and move at much the same pace, around 180 to 240 bpm. Songs run longer in Bay Area thrash: usually 4 to 7 minutes, against 1 to 2½ minutes in crossover thrash. To hear the difference, play Metallica next to D.R.I. Bay Area thrash comes from the metal side of the tree and crossover thrash from the rock side, and Bay Area thrash came first, by a year.
