can anyone provide a good review and comparison in terms of user experience for iwork vs polaris?

Never used iWork before so sorry I can't post any review about it. But I had experienced many office apps before. From 1st one, office2 hd ($7.99), smart office 2( get free), documents to go ($14.99) and lastly polaris office ($12.99).

I need office apps coz use it oftenly in university, do work, read notes, presentation... But mostly major typing still at laptop there.. But when going to campus, I'm like to carry ipad only coz light. And I can read PowerPoint.

Office2 HD, simple UI and fast.. But can't actually show the same content what in window laptop. Smart office 2, difficult UI, ads pop up always, but show better than office2 hd, but the graph, shape in word,PowerPoint, will gone and jumping there and here. Failed.

Documents to go premium, bought it coz it famous. But the apps is not worth as thevalue. Same problem here, can't show the actual thing like window.

Polaris office.. Bought it recently, it's archive what I need. The format, graph, picture, shape, all the things, same as what can I view in window laptop.. Some more it got 1 function can do annotation on PowerPoint slides when u are in full screen mode. I can highlight all the important things while in class. Best and recommended. Simple UI.

iWork, never tried, coz I worry not compatible with window format..
