There are vast differences in quality among deinterlacers. Better deinterlacers employ some version of optical flow. They fill in the missing lines in a field by reference to information in that field plus fields before and after. Software implementations generally run slowly.
At least as great quality differences should be expected from double framerate deinterlacers as from same framerate deinterlacers since the former may be achieved by two applications of the latter. I explained this recently in another forum. (Note that we say 50i and 60i, not 25i and 30i, in that other forum.) At the end of that post are links to an interlaced original (from DV-PAL) and its high quality double framerate deinterlace. People might wish to test if their methods achieve similar quality.
