The HTC U Ultra is the company's latest flagship, with a unique liquid-metal finish and a range of eye-catching finishes, the U Ultra is an attractive big phone. Packing well-rounded, powerful hardware and interesting features like a secondary notification panel and 24-bit audio (sans headphone jack), this phablet may be worthy of your consideration, though most reviewers are not keen about its premium pricing.
The HTC One X9 is a classic example of a mid-range handset. It has marginally better hardware than budget offerings - a 5.5-inch 1080p display, a Helio X10 SoC, 32 GB of storage, a 13-megapixel camera with OIS, and a metal build - but it just doesn't do enough for the price. It's not a terrible phone, but it's simply too expensive.
