Of course 830 have better build,camera,im not sure bout battery though
In term value for money,u get more for 735,the different is a massive rm450,for rm1300,snapdragon 400,720p on 5inch even on wp8 is slightly overpriced(you can get snapdragon 800/801 beasts,1+1,lg g2 with ois with that price)

I do agree 5mp selfie on 735 is a waste though  if they give up on that and put decent 8.0mp,that would be great

Price check on lelong,l830 sell for rm1.4-1.5k,that's not far from the great L930 and L1520
