Have tarmac, well worth the money, although moss will grow if drive under shade of trees. But I have grown to not mind the moss. Price of tarmac I would imagine should have gone down from when we did our three years ago.
804 is only a temporary job (in my mind) messy for children, weeds etc.
If u opt for tarmac make sure you get a "professional" company. There is nothing worse than badly laid tarmac. If ur in Galway/Mayo directions ill pm u a company who did three houses in my family and not one complaint.
Good luck with your drive.
