for alliance,
human: sword and mace expertise (+3), spirit bonus, rep gain bonus (huge), slight increase in stealth detection i think ( i know perception is gone), and pvp-type trinket in pve. a very solid choice for dps pvp or tanking. The only thing i could argue against is if their trinket ability shares a CD w/the 2 minute trinket, and you are a pvp min-maxer you would want the 40k honor trinket for the extra resilence.
dwarf: treasurefinding, stoneform, mace specialization (+5) frost resist.
great for tanking and ok for pvp because stoneform breaks bleed/poison/disease effects. for max benefits you're pidgeonholed into 2h maces. dont know how easy it will be to obtain them. a fairly solid tanking race
gnome: escape artist, expansive mind, arcane resist.
very subpar for pve. the mind will give very little to spell crit cause DK have so little. arcane resist can be decent but too situational. escape artist for pvp can be great because DKs have trouble with classes snaring them.
night elf: shadowmeld (vanish-like effect), quickness (reduces chance to be hit 2%), wisp, elusiveness, nature resist.
best pve tank build, decently good for pvp as well. dps not so great. shadowmeld is awesome for pvp and for solo pve when you need to get something off of you. if you pull hate as a DPS you can use it to hopefully get some time for the tank to regain aggro. this is the best pve tank build because of quickness and nature resist.
draenai: 1% bonus to spell and magic hit rate, gift of the naaru, shadow resist.
decent. overall decent. not bad at all because the 1% bonus to hit works for spells and melee for the whole party and compared to the expertise talents it lets you use any weapon. the benefit isnt as good as expertise for a tank though. gift of the naaru is a great solo talent, and for a dps dk its very good too.
because heroic presence doesnt stack, most raids usually have a draenai in them anyways for heroism, so really this wont bring much for a tank. in pvp kinda either way.
personally i'd go human or night elf.
