If you're in the market for an e-reader, you've no doubt read some reviews, checked out some user feedback, maybe even spoken with friends. That's all well and good, but sometimes you just want to put the leading candidates side by side and see which one wins the day.

That's the idea behind ReaderRocket, a seriously nifty tool that compares e-readers and gives you a complete rundown of specs, features, reviews, and more -- all so you can make the most informed decision possible.

To get started, either choose one of the existing comparisons, or type a brand/model name into each of the two available fields and choose the desired products from the dynamic selectors that appear. (It would be nice if you could browse a brand list, but ReaderRocket doesn't currently offer that option.)

Once you've made your picks, the site gives you a truckload of data, but presents it all in a clean, logical, dare-I-say-sexy layout. As you can see in the above screenshot, for example, the head-to-head between the Kobo Glo and Kindle Paperwhite gives you an at-a-glance look at their physical size differences, plus basic specs like screen resolution, release date, and pricing.

Scroll down a bit and you'll see some conclusions based on criteria like display, performance, bookstore (i.e., the quality of the supporting ecosystem), and reviews, plus a declared winner.

Further below, ReaderRocket serves up sections like Differences, Competition (other models worth considering), Performance, Features, and Comments. It's a fairly amazing breadth of content, with pretty much every stitch of information you could hope for.

Interestingly, the scope of products includes quasi-tablets like the Kindle Fire HD , Nook HD+ , and Kobo Arc . But the site stops short of including real tablets like the iPad Mini and Nexus 7 .

Even so, this is a great resource for e-reader shoppers, and a downright fun way to compare the differences between models.
