In October, three musketeers in the smartphone market rushed before the eyes of smartphone watchers - Motorola Droid Razr, Samsung Galaxy Nexus and iPhone 4S.

Motorola took the wraps off Droid Razr last Tuesday. It was available for pre-order on Oct. 27 and hits Verizon Wireless stores early in November.

Samsung Galaxy Nexus, the latest Samsung and Google flagship smartphone, which  was unveiled in Hong Kong on Oct. 19, is likely to be launched in November in the United Kingdom.

Apple's iPhone 4S, unveiled on Oct. 4, just a day before the company's co-founder Steve Jobs died, smashed its previous sales records by selling 400 million devices over the launch weekend.

However, Motorola Droid Razr got most of the attention for its thinness and weight. It boasts of dual-core 1.2GHz processor, 4G LTE capability and 4.3-inch Super AMOLED Advanced display. Samsung Galaxy Nexus features Ice Cream Sandwich, dual-core 1.2 GHz processor and 4.65-inch AMOLED screen, while  iPhone 4S features iOS 5, 8-MP all-new camera and iCloud.

So much stunning features may have put you in the difficult position that you have no idea which device you should buy. The following chart, however, may help you decide.
