I use EDIUS because it doesn't need to transcode my 5D h264 videos and works them nearly as good as if they were transcoded to something else. Sony Vegas also works quite well with native camera files without the need to transcode. Transcoding takes time, and storage, unless I throw away the transcodes after I am done. For budget/time friendly video enthusiasts I would never recommend transcoding. If two companies can create software that works with the native camera files efficiently, so can all the others.
