hop up unit

so i get what the hop up unit does and how it works

i already intend to order myself a guarder clear set and a shredders concave spacer for my G&G MP5 off of, i figure for the small price its a great upgrade

but i was wondering what about the actual hop up unit?? i see them for sale, but am unsure of what possible advantage or what it could do for you?? is there any advantage/difference between different hop up units?? or possibly differences between the metal and plastic hop up units??

besides the obvious of it being a replacement part if something breaks or gets lost, i dont get why you would replace a stock hop up unit....any ideas??
