Hi,
This has been long discussed in this forums and probably this question is raised once a week. The answers are basically always the same.
IE Plugin it's a product that made sense when web technology didn't allow HTML5 or Ajax. As the name implies, it's a plugin (meaning, a different piece of software you have to download and install in every client computer) and it only works with Internet Explorer. Technically, it's a set of DLLs that allow some ActiveX to be executed on your computer. By nature, this is not allowed in other browsers like Safari, Chrome, Opera or Firefox (same with mobile browsers in iOS, Android and even Windows RT with the IE app).
Basically, the Plugin is a thin version of QlikView Desktop or thick version.
Ajax client does not require any installation other than a web browser. Well, a web browser able to display Ajax pages, meaning that it allows rendering HTML and CSS and Javascript.
Which one is best? Up to certain releases of version 10, I'd say Plugin. From version 11 on, Ajax and only Ajax except for those cases where, for whatever reasons, Plugin must be used.
In regards to how to access each document, you can set that in the Server. Using the QlikView Management Console you can set in the User Documents which one is going to be available only for Plugin (therefore not visible by users with other browsers different to IE), which one is going to be available only in Ajax, and which one will be available to download offline using the native iOS app.
Additionally, and providing the documents are available for all clients, you can set your profile in the AccessPoint to use a preferred client by default. This is set on the "Edit your Profile" link in the main AccessPoint page, top right, right by your name. So it may happen that in one computer you click on a document that is open in Plugin, and the very same document is open in Ajax.
As a general recommendation for all your developments: use Ajax.
Hope that helps.
