Acrylic backboards are an alternative to glass, and certainly get the job done, but they don't really compare quite as well to the firmness and rigidity of a glass backboard.
When you are looking a basketball hoop, performance means how rigid the system is and how responsive the rebound is. That is, how well the basketball bounces back at you when you bounce it against the backboard. By that standard, glass backboards are hands down the best one to choose. While acrylic backboards certainly get the job done, they don?t really compare quite as well to the firmness and rigidity of a glass backboard. This top notch performance is the reason why glass is still the official material of NBA and College level basketball backboards.
In almost all cases, the acrylic models are cheaper than the glass model backboards. This Is because the process that goes into producing the high quality, break resistant, heat tempered glass is just a lot more complicated and expensive than producing a similar acrylic backboard. So if you are simply looking to get the best high end basketball goal you possibly can at the cheapest price, then acrylic is probably the best way to go.
