What is the best race to become a vampire on oblivion

11DBHK: Dark elf (imo) because while the dark elf has decent stats as well as great blade, marksman, destruction. if you also decide to master alchemy and sneak skills, you have a really potentially dangerous character
the dark elf can also make great use of hunter's sight and won't be bothered too much by the weakness to fire since they boast a resist of 75 right off the bat. even as a full vampire you'll still have a 25 resist.
