Apple iPad 4 vs Samsung Galaxy Note 10.1 vs Dell XPS 10 :Who is the best?

W.A.Khan,                                                                                                                                                                                                                                                                                                                   Apple iPad 4                                                                                                                                            The newest iPad's faster A6X processor adds extra system speed and graphics power. Improved worldwide cellular compatibility makes the LTE model a more appealing proposition. And the iOS App Store remains best in class, with the widest selection.
But, The fourth-gen iPad is otherwise identical to its recent predecessor -- same size, weight, and Retina screen. It's heavy to hold in one hand, and most older accessories won't work without investing in a pricey Lightning adapter.
The bottom line: The latest iPad adds several tweaks and improvements to secure its position at the top of the tablet heap. It's better all around, but third-gen owners need not apply.                                              Specifications

The S Pen Stylus is a unique addition.
But, Only a limited number of apps make full use of the S Pen and some of the ones that do can be buggy and confusing. Some S Pen features aren't enabled by default and others don't work properly.
The bottom line: The Samsung Galaxy Note 10.1 is the best Samsung tablet yet. If you can get over its somewhat high price, it's a sound Android tablet investment.                                                                       Specifications

But, There are a few annoying performance bugs. The base tablet doesn’t have as many ports as the Surface RT. It lacks a kickstand and its keyboard isn’t as comfortable to type on.
The bottom line: The Dell XPS 10 is a valiant effort at a Windows RT tablet but doesn’t pack enough value into its base package to favorably compete with the Surface RT.                                                                Specifications
