motor should be less than 1000kv .Both of your motors are good from links given info.
but i would personally suggest the following dt700 or dt750 they produce around 950g of thrust on 10x4.5 props consuming around 13amps at max. , really powerfull .And if u wanna 4 motors for your quad they are well under $50 ,total of more than 2700g of effective thrust for your 1200g quad. check the link.
