WotLK Frost or Unholy DPS

[Dayquil]

I have never played a DK on Wotlk, I love it on MoP and I wanted to try it here, so which is better for 3.3.5 PvE wise. I'm frost on MoP realms and do pretty well with it, but WoTLK and MoP are two completely different expacks so IDK which is better.

I'll probably get one of the two 2h swords on pointshop as weapon, aseirs edge and stormborn something i think. Both are 107 points... unless there is a better one to start off with for unholy or 2 1hrs for frost

As for burst and in a single target fight, frost will outdps unholy most of the times, especially if those fight don't require movement (like DBS). In AoE fights you'll rule and those with a lot of movement going around, unholy will probably outperform frost. So it's a matter of preference.

Yes, Aesir's Edge is probably the best you can get if you wanna go with a sword. Other 2-hand option could be Hammer of Crushing Whispers (mace). As for frost, Nighttime x2 is your best bet for dual-wield.
