MiniDV. No question. The DVD camcorders automatically compress to MPEG2 which results in loss of quality. The Hard Drive camcorders compress to MPEG4, which is even more compressed than MPEG2 and some (JVC Everio) are buggy when working with current NLE software. MiniDV records in DV-AVI which is going to give you the best quality, as long as you capture and edit in DV-AVI and only compress after you're done.
