Latest issue of Which? magazine recommends the mini-DV format simply for ease of editing on a PC. I've been using it for years with my now aging Sony PC100, and the results are excellent.
As an aside, for editing I now use Magix Movies on CD & DVD, which is a combined editing suite and DVD/CD burning software. Courtesy of the well-known emporium CP World (sic), it was wrongly priced at a penny under £15 (should have been £40), so of course they had to sell it to me at that price! BARGAIN. Never complain about them again.
Tip. When buying anything in these megastores, always root through all the boxes in the rack. Invariably you will find one at the wrong (lower) price, left over from some special offer.
