Like said glass doesn't scratch as easy, where I live you would have to get a tank custom made to get it made in acrylic which would cost more, glass tanks are cheaper, and more durable. Plus I just plain old like it.
Glass every time. Acrylic is plain ugly (IMO ), expensive, hardr to come by and easily scratched although it can be made into interesting shapes it will always look tacky (IMO again obviosuly ).
For small tanks like my betta ones, acrylic is great but when I get a bigger one it will be glass. I am a klutz and would probably put a nice big scratch across the front of an acrylic.
