Difference between Acer E5-521 & Acer E5-551 with same specs.

I have a doubt. I'm gonna buy a new laptop, and for the price that i can afford i found 2 different models that i like but are almost the same, same specifications, same CPU, HDD, Screen size, RAM, GPU, all seems the same but have a different model name. The 2 models are the ones that are in the Title, the Acer Aspire E5-521, and the Acer Aspire E5-551. Both have the A4-6210,4GB RAM, 500GB HDD, battery of 6 cells, screen of 15,6" with same resolution, webcam, DVD-DL, USB x3.0, HDMI, same Wifi,same Lan, same bluetooth, ... i cant find any difference but the price that in the E5-521 is 20 bucks cheaper. So my question is, anyone knows what is the difference between these two models?... If anyone could help me i would appreciate it a lot, more if you do it quickly, 'cause i need to buy it as soon as i can. Thanks for your time anyway.

I know these are different specs but I think it's just the display is different. The 551 is better.
