Documents to Go is an excellent application suite. Not perfect because no MS Office emulation is but it's well worth the purchase price.
I'm not familiar with "Pagely." If you meant "Pages," it's a reduced function version of Apple's word processing application for the Mac. And while it reads MS Word documents, that is not its primary function. I've never used Pages but my impression is that it's a relatively simple word processing package with its "sizzle" lying mainly in the ability to combine words and images in an attractive manner.
