.jad files contain a set of attributes enabling the identification, retrieval, and installation of MIDlets. .jar files are compressed file package for classes and data. They're a special .ZIP format, and is based on the standard ZIP file format with an optional manifest file. In simpler words, .jad files are for MIDlets (which are applications that use the Mobile Information Device Profile), while .jar files store many files inside and are more widely used. Since you haven't stated what kind of file you want to download, I can't properly answer your question. However, I think .jar would be better. Hope I helped. :)
