Personally, I've used all the major office suites for Android: Quickoffice, Docs To Go, Google Docs, Polaris, and Office Suite Pro. All of them have their strong and weak points, but I can say with confidence that Office Suite Pro does indeed offer everything you'd need for light word processing, presentation creation and editing, and even some advanced spreadsheet functions.
A recent design update brings it up-to-date with Ice Cream Sandwich ROMs, and its tablet interface is decent on the EVO View. And at $2.99, the price is right for almost everyone. Of course, you're not going to get the full Microsoft Office experience here – no Android app offers that yet – but if you find yourself limited by Polaris and Google Docs, definitely give this one a try.
