The bottom line is: if you are shopping for the best smartphone, then look no further than the Galaxy S4.

The fight is on. It is really on now. HTC played the first stroke, with that gorgeous HTC One. Samsung responded with the Galaxy S4. Fair amount of criticism has been showed S4's way for the plastic build. The aluminum unibody on the HTC One has taken the benchmark a tad further, without doubt.

Excellent performance; Crisp and vivid display; Plethora of unique features; Good battery life; Camera works well in good light

Lacks that premium feel; Too many features can confuse

The Galaxy S4 is a remarkable piece of technology, offering power, functionality and a solid platform for mobile gaming. Although it misses out on the much-hyped Exynos 5 "octo-core" chipset, the replacement Snapdragon 600 is almost as adept.

This phone is the most complete package. I came off from an iP4S and grabbed the HTC One, because of the metal casing. After I had it a week, I realized i wanted a bigger screen. The front speakers just wasted valuable space. I also realized the metal wasn't that big of a deal.

Beautiful colour and slim design containing high technology. Easy to use and configure personally. Thanks Handtec. Great update from an iPhone 4S.

It's fair to say that Samsung's success with the Galaxy S3 has been nothing short of astonishing. The handset even gave the lauded iPhone 5 a run for it's money in terms of pure numbers, and for good reason.

Although the S4 will probably triumph in the sales arena, the HTC One is still our pick.

Brilliant display; Great performance from the octa-core CPU; Runs on the latest edition of Android; IR blaster functionality is handy; Excellent snapper with plethora of camera and video features; Good battery

Plastic build doesnt match the premium feel of rivals like the HTC One and iPhone 5; Low-light photo quality is no match for rivals such as the Nokia Lumia 920; Capacitive buttons cannot be seen in direct sunlight on the white S4

Are there no limits to what the Galaxy S4 can do? Just yesterday, it helped save the world from an alien invasion, right before giving birth to a little one that, we're told, will eventually be known as the S4 mini. ( Editor: go easy on the puns there pal ).

Superb screen; versatile camera; speedy performance; software features

The range of features could get confusing; mixed success with some features such as Air Glance and Air call-accept

A brilliant smartphone from Samsung that from initial sales is looking to upset the market and outsell the Apple iPhone 5.

- Beautiful screen; - Very fast & powerful; - Great camera & features

- Not cheap

Samsung's Galaxy S III is a very sweet Android smartphone , arguably the best of its generation. So you have to wonder what Samsung could do to meaningfully push the envelope in the Galaxy S 4 now available at some carriers (Sprint and AT&T) and soon to be offered at others (Verizon Wireless and...
