All 3 weapons are pretty nice. If you are a human you should go get the sword because humans got +5 sword skill as racial. If you aren't a human you should go for the axe since it got the best DPS/Max damage. As Arms spec warrior the speed difference doesn't matter that much. For PVP the axe is best, the sword might be a little bit better for PVE in some situations, same counts for the hammer.

I dont know, everyone says ""Stick to the axe, take the axe!"" Actually, the axe aint better than the others. The sword hits fast, so it's a good choice aswell. The club, that I havent seen a single warrior with, is really good. I had it on one of my warriors just to be different.. And all of you say ""AXE FTW"" That club kicked ass. I say, go for what you like. They are all good just in different ways.

Excellent weapon, good stats and as mentioned above, will last you to level 40. I also remember this was the first weapon I ever saw in the game, because my friend had it on his level 40 orc warrior at the time. I loved the look of durotar then, now it seems less charming.. ah well.

If you are a prot warrior, I still recommend doing it. I believe the chain is worth it for experience as well as for some gold, for when you sell the reward weapon.

You wont be able to get this solo untill around 40+. with same lvl help in a group at 38+ and with high lvl help you could get it as soon as you have the quest for it ofc. i got it at 40 and it lasted till Ice Barb Spear from AV quest.

I'd like to add the following information: the pre-crit per-hit damages* of each weapon, prior to any talents:

Whirlwind Axe: 102-154 damage, average 128
Whirlwind Warhammer: 97-146 damage, average 121.5
Whirlwind Sword: 82-124 damage, average 103

Pure Damage Benefits of WWA over WWWH:
average 6.5 more damage per Whirlwind, Mortal Strike, or Slam
average 3.75 more damage per Overpower
1.3 + AP/350 damage per tick with Rend
3.12 damage per tick with Deep Wounds

Pure Damage Benefits of WWA over WWS:
average 25 more damage per Whirlwind, Mortal Strike, or Slam
average 12.5 more damage per Overpower
5 + AP/140 damage per tick with Rend
12 damage per tick with Deep Wounds

Pure Damage benefits of WWWH over WWS:
average 18.5 more damage per Whirlwind, Mortal Strike, or Slam
average 9.25 more damage per Overpower
6.17 + AP/233.3 damage per tick with Rend
8.88 damage per tick with Deep Wounds

These are the only warrior attacks which benefit from higher average weapon damage at this level, and white damage should, over time, be the same all Whirlwind Weapons. Myself, I see the racial expertise benefits as more useful than the slight pure damage lead that the WWA has over the WWWH for humans and dwarves, but at least now the exact benefits are spelled out.

* I purposely refrain from saying ""top end damage"" because people are incorrect in using it. What matters is the average weapon damage, which is just the average of top and bottom damage. This is more accurate, since instant cast attacks don't always use the top damage, they randomly determine the damage between the min and the max.

maybe that's because it's a follow up to the BERSERKER STANCE quests?
where in the quest text the guys is like 'let's get you a weapon for that BERSERKER STANCE?'
