I've used both lexan (polycarbonate) and Plexi-glass for a variety of projects over the years. I've found polycarbonate to be more resistent to cracking than plexi-glass. In addition, polycarbonate tends to bend rather than shatter into sharp shards like plexi-glass. Yes polycarbonate is more expensive, but well worth it with the safety factor.
