Speaking as a warrior, a lot of Syrsa's analysis is incorrect.
For your typical high-end warrior doing raid DPS, +1% haste is probably a net 0.5-0.6% increase in overall DPS. (Why? High-end warrior does about 50% white damage and 50% yellow damage. 1% haste is to white damage and on-next-attack, i.e. Heroic Strike and Cleave, so slightly more than the 50% white damage is accelerated).
Killing blow timing is irrelevant for PvE raid, all I care about is doing more DPS over time and what enchant allows me to do that.
Most raid boss fights are well over 200sec (or 400 seconds for that matter), so you will see the extra swings. Trash kills are obviously faster, but less critical.
The last argument "even less where it's a matter of life or death" is irrelevant to any discussion of enchants. You might as well say "don't bother getting any enchants they only increase your damage a little bit, so it's not worth it" ... the point here is not how small the increase is but rather for the specific slot which is the best enchant.
For warriors doing dps with high-end gear, the enchants on gloves are valued approximately as 1%haste >== 15agi > 7str >> 7agi. 15agi is very expensive though (150-200g), and 1% haste is very cheap (10-15g). For tanking gloves, 15agi is better, of course, since it adds armor and dodge along with crit. +threat is better still.
Ironically enough, it turns out that for DPS warrior, the looked-down-on weapon counterweight, +haste to gloves and libram of rapidity are pretty excellent additions, especially if you have them all. Your baseline damage has to be pretty high (BWL-ish gear) before this is true, and you should be fury build to make maximum advantage of it.
(Ignore all this if you are concerned with PvP mostly, since your ability to do sustained single target damage is basically zero -- get +agi)
