arcylic will be more visible for the scractes and glass is more scracth proff as some forumers said. pricing wise is depend on the showroom you visit. for example if the showroom you visit is more on arcylic will sure he/she will said arcylic is better and bla bla bla just to hard sell it's own products so as the glass 3G. at the end you have to trust your own eye sight and just have to think about it wether u want more careful maintenaice or less. but bare in mind the glass one normally was not in tempered glass coz the price will sky high one. both have its pros and cons.
