I beg to differ. AFAIK, Plexiglass has been around much longer than Lexan. Lexan is stronger than Plexiglass but Plexiglass is more than strong enough in most applications. The biggest problem with Lexan is it is more prone to UV damage usually seen as crazing. Lexan also has less surface hardness than Plexiglass so tends to scratch and disfigure easier. Plexiglass will usually cosmetically outlast Lexan. Was just on a boat with Plexiglass windows in their hard dodger. After 10 years, 3 of them in Mexico and the rest in SF Bay, the plexiglass looked great. Haven't seen Lexan hold up that well.

In most instances, there is no need and reasons not to take the economic hit of going with Lexan over Plexiglass.
