Polycarbonate vs Acrylic etc

Well depends on what you are most concerned about.

Polycarbonate is very sensitive to UV light degrading it... so you have to be sure it is loaded with UV stabilizers... which many Polycarbonates don't have.
There are versions designed for use as windows or shades which have the stabilizers and have a special (ultra thin) hard coating for scratch resistance as is is subject to scratching and abrasion which will dull it. Also, polycarbonate is hydroscopic and absorbs moisture... making it hard to form into shapes unless dried. Forming is thermoforming or it can be bent in a press brake mechanically cold.
But it is incredibly tough stuff.

Acrylic does not have the UV problem and is more scratch resistant but you should get the scratch barrier protected if you have cosmetic concerns. It does not have the moisture absorbing issue either. But is more fragile and likely to break to breakage so you have to make it thicker. It is easily thermoformed but cannot be mechanically bent or formed as it will break.

In either case DO NOT EVER expose to Windex or other ammonia based window cleaners as they cause stress cracking. So you have to use special plastic cleaner or soap water and vinegar.

I think you made a wise choice...
But get a little thicker as it makes it more durable... go about 50% thicker than the polycarbonate and that will make up the the breakage issue. You can get the special coated scratch coated versions too if you use it as windows... and even tinted.

I should be clear the scratch coatings on either material are not a film or liquid coating but hi tech vacuum deposited rare earth materials that are very hard but microscopically thin.
