Asus ZenFone 2 ZE550ML vs ZE551ML : How Exactly Are They Different?

As soon as our airplane from Indonesia landed in Manila yesterday and I turned on my phone's mobile network, I immediately got bombarded with messages from my friends and readers in the Philippines who are eager to learn more about Asus ZenFone 2's local availability and pricing details.

I received a ton of questions about this amazing handset but the one inquiry that kept coming up was about the main difference between Asus ZenFone 2 ZE550ML and ZE551ML. You see, Asus is set to release four variants of their flagship model in South East Asia and the most affordable version is the 16GB ZE550ML, which will sell for only 2,699,000 Indonesian Rupiah or Php 9,639 (with current conversion) when it hits store shelves come May or June this year.

Asus flashed these pricing information cards for the 16GB ZE551ML and 16GB ZE550ML and apparently, the data presented baffled some of my readers as the two handsets appear to be largely the same. Well, the truth is, they are very much alike but they have one key difference.

According to Mr. Gabriel Paolo Padit, Asus Philippines' PR Specialist, the 16GB Asus ZenFone 2 ZE550ML has the same features and technical specifications as the 16GB ZE551ML but the former only has an HD 720 x 1280 pixels IPS display compared to the Full HD 1080 x 1920 pixels IPS screen of the more expensive model. ZE550ML will also have a 13 MegaPixel PixelMaster autofocus camera with Dual Tone LED flash. Essentially, they're exactly the same except for their displays.

So between 16GB ZE550ML and 16GB ZE551ML, which Asus ZenFone 2 model do I recommend? Based on their recently announced SRPs in South East Asia, I believe the two variants will be separated by a margin of just Php 1,000. If you think such amount justifies the Full HD display on the ZE551ML, then go for that model. If not, go for the ZE550ML. If you ask me, I'd say you should just spend a bit more and get the version with the more crisp and clear screen so you can better appreciate photos and videos taken using the phone's stellar PixelMaster camera, which is one of Asus ZenFone 2's main selling points.
