Best office suite for Android?

I need to have a word processor for my Android tablet that has almost as many features as on the PC, and that displays all kinds of Word documents (doc, docx, docm, password-protected, complex,..) faithfully.

I already tested Documents To Go, QuickOffice Pro, and Polaris Office, but they all have too limited features, and I had problems opening several of my Word documents, others had screwed-up formatting.

I also need a spreadsheet, and a presentation graphic software for Android that deserve the name, the above mentioned don't.

Recommendations appreciated.
