I like both glass and acrylic tanks, but would choose acrylic on a tank 150g. or larger just for the huge difference in weight and the fact I'm paranoid my tank will go crashing right through the floor, LOLOL. I remember that I could lift my 55g acrylic tank and carry it around with two fingers.
I also think there's a lot of myths about acrylic tanks such as yellowing, very easily scratched, crazing, bowing, melting, etc. I had a 55g and a 125g acrylic tank both for over 10 yrs. and neither one bowed, crazed, yellowed, melted, or anything else, in fact they both looked nearly like new when I recently sold them. As far as scratches go, they don't scratch unless YOU scratch them, you just have to be careful not to smash rocks into the sides and not get substrate between the acrylic and cleaning pad when cleaning algae.
