Glass is definitely not for everyone
Glass can be very fragile too,where plexiglass(acrylic,so it's a lightweight but extremely durable plastic)is extremely sturdy and would take far more to break.
It is a personal choice though,but overall either will work just as good but you can expand glass tanks much easier as they can be taken apart where it's not easy to take apart acrylic tanks which are generally bonded on a molecular level instead of sealed together.
