A pentile screen uses fewer than 3x pixels sub pixels to make up the screen. Most pixels have R/G/B sub pixels to make a color, a pentile screen has pixels that have a sub pixel for R/G/B, but some are larger and shared with other pixels.
Here's a closeup of the Galaxy S3 vs. HTC One X screen:

This causes some colors to look odd on the screen and causes strange color changes at different angles. On the S3, reds look like they are floating on top and blues and blacks look like they are in the background in a kind of eye popping 3d effect, but not the good kind that makes you go "wow". Whites turn a strange yellow if you don't look directly at the screen. Not everyone has eyes good enough to see these things but I think most do.

I don't think any of them actually beat Apple on design, but they have some neat tricks. The Galaxy S3's camera is amazing and the backing feels very nice to the touch and the blue shiny stuff is very pretty. The One X has external charging pins so you don't have to plug in and an amazing looking screen.
Overall though I haven't used an Android that felt as solid or as polished as Apple hardware, especially the iPhone 4/4S. The metal and glass on that feels very solid and the switches are great. Go grab an Android and just press the power button then press it on your iPhone. World of difference. I also think that Apple has the best OS. Android has some interesting features for what I consider to be edge case usage, but most of that stuff just gets in the way. The two deal breaker apps for me that weren't on Android were Nike+ and Flipboard, well, both are on Android now.
If the world operated on absolutes, then I think the only phone people would buy would be the iPhone 5. Instead, an iPhone user is going to look at that and say to themselves, "You know, even though I know its the best possible phone for me to buy, I'm bored with it, and I know that this other device can basically do the same things with less polish, but it has X." Say X is expandable storage or an exchangeable battery or a larger IPS display. Basically some WOW factor to get the consumer to ignore the OS upgrade update rate, or the pathetic battery life, or the less smooth interface, or the plasticy build quality.
I'm sure a lot of iPhone 5s will be sold, that's not what I'm getting at. I also think a lot of Androids are going to be sold to bored iPhone users, even tho those same users are massively satisfied by their current device. Ironic isn't it?
