I think much depends on if you want to create a model that is reasonably accurate to the original.From an accuracy point of view the Deagostini is good closely followed by the Billings as the Billings was reputed to have an accurate hull form.The Sergal not so but the Corel is way off in some respects.
If you want a nice display model, not massively concerned about the historical aspect and don't want lots of additional work,I would have to disagree with Brian and say Corel.Sergal would have pipped Corel to the post had it not been for the alterations they have made to their kits.Sorry,but I am not a fan of the imitation wood planking on the decks and dubious gunport design.At least you get planking material for the decks in the Corel kit and it does cost a good deal less than the Sergal.
Personally,I feel the best all round kit on the market at the moment is the Deagostini partwork but it also works out the most expensive.Have you contacted the publisher to find out how long before it is available again?
Kind Regards
