I would go with Acrylic. Less dense with better clarity, less seams, less likely to leak, and more shatter resistant than glass. Negatives are they scratch easier, more expensive, but easy care with water and microfiber towels.
Either way you go, make sure to properly level the tank on the stand before you add water. If the tank isn't properly aligned, it will crack over time, especially a glass tank.
Just remember that aquariums are essentially sewage systems. They are designed to grow beneficial bacteria that will remove toxins put out by the fish, food, and waste in the form of Ammonia and Nitrites. Nitrates are removed mostly from partial waters changes, 30% a month, I prefer 25% every two weeks myself.
