Replying to Differences between Camcorder Formats?

So i think my canon mini DV camera is toast, it got moisture damage last year, lots all of the best footy, got that fixed but now the tape got all caught up inside and i think i may have fucked it over trying to get it out. Basically ive had it with stupid tapes and was wonderig the differences in quality and ease of editin between Mini DV, DVD, and Hard drive, im kinda leaning toward hard drive but let me know what you think, thanks
