Which lip gloss is better? l'oreal glam shine or mac lip glass?

i am really interested in lip glosses that have some glitter to them. i recently purchased l’oreal glam shine… the effect is very pretty… but i have seen photographs of those wearing mac lip gloss (At least i think it is mac lip glass)- these photos show glossy, very shimmery, glittery lip colors that are obvious even in photos. so i just want to know which is better… if the effect created by mac is better than loreal
