It's natural to compare the recently unveiled smartphones - Samsung Galaxy S5 and HTC One (M8) - as both will hit the stores almost the same time. The former will be released on 11 April in more than 150 countries, while the latter has been made available online at U.S. carriers and at Verizon's stores since Tuesday and would hit the stores in April first week.

Interestingly, the Taiwan-based smartphone maker had earlier challenged Samsung Galaxy S5 by tweeting on its handle that people, who go for the device before the release of HTC One M8, will regret.

Critics are all praise for HTC One M8, but most of them are of the opinion that Samsung Galaxy 5 and the upcoming iPhone 6 would win in terms of sales.

Samsung Galaxy S5 has features like water resistant and heart rate monitor, but HTC One M8 is superior in terms of software and hardware design, according to Joanna Stern of The Wall Street Journal.

"In a fairy tale, the HTC One M8's charms would win the hearts of more phone buyers. But in the real world, the giants - Samsung and Apple - will probably once again win in sales," wrote Stern in his review of HTC One M8.

HTC One M8 is beautifully designed and constructed, is fast and has a great display, and uses one of the best manufacturer-customized interfaces, but it will be difficult to compete with the monstrous advertising budgets of Samsung and Apple, wrote Chris Devies of Slash Gear in his review of the HTC flagship smartphone. 

The HTC One M8 has been described as the "best smartphone the world has ever seen" by BGR's Zach Epstein in his review of the device. He wrote that it is superior to HTC One from design to the power of its components, but is skeptic if it can succeed in drawing customers of Samsung and Apple. 

"The HTC One M8 is a phone that's supposed to offer the best of the smartphone market, one that will survive the onslaught of the iPhone 6 and the Galaxy S5, while preserving HTC's heritage and bringing the bottom line closer to something more healthy," wrote Gareth Beavis of Tech Radar in his review. 

Gordon Kelly of Forbes described the HTC One M8 as a winner and wrote in his review that the device would give a still competition to the recently unveiled Samsung Galaxy S5. 

However, HTC One M8 may not be able to beat Apple and Samsung in terms of sales, despite praises from the critics. HTC One, which won the 'Best Smartphone of 2013' award at the recently concluded Mobile World Congress 2014 (MWC 2014) in Barcelona, too was critically acclaimed, but iPhone 5S and the Samsung Galaxy S4 did better in terms of commercial success.

We leave it to the readers to decide which of the smartphones - HTC One M8 or Samsung Galaxy S5 - they think is better with a table highlighting the detailed specifications of the devices.
