mi4c will be a better option if u get mi4c with 3gb ram and 32gb rom.

mi3 specs is way diff than mi4c, u can't compare mi3 with 4c la

mi4c in terms of proc and graphic all winning honor7. ram 3gb same.  mi4c camera software and processing better than honor7 20mp even though only have 13mp.
Honor 6 and honor 7 using  same graphic processor, u can see a lot review on honor6 play game will lag problem.
in term of OS, IMHO miui is way better than EMUI, but this may due to personal preference. 

mi4c only lack of the fingerprint sensor n metal unibody,  but mi4c have the side tap function which is very cool though.

now just that mi4c dono when will launch the 3gb ram high spec version in Malaysia
