Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
Real contrast ratio (not what manufacturers report but what an independent observer measures, like some of the better publications) makes a difference. For me, in a controlled environment, more is always better. On the other hand, for watching TV in a casual way in a regular living room, it doesn't make a big difference beyond a basic level. So I'd pay top dollar for the best real contrast ratio for my critical viewing (Kuro), and I'd pay no premium for my casual viewing (Vizio).
The Honda and the Mercedes both get you from point A to point B. They are not the same experience. Only you can decide what value to place on the difference.
