Contender's gears vs. Crafted Dreadful gears

Contender's gears vs. Crafted Dreadful gears

My toon is going to hit level 90 very soon and I am looking for gearing
guides. Multiple sources point me to this guide, where it is stated that
if I go the crafting route, I should get the Contender's gears, which are
iLvl 450 pieces. There are several other guides also mentioned the
Contender's gears.
Then I searched on the AH. Instead of the Contender's, I saw a lot of
Crafted Dreadful gears that are iLvl 458 items and has better stats. It
seems these are better than Contender's in all aspects as long as I can
afford them.
I am looking to confirm if the gearing guides did not mention Crafted
Dreadful gears because the guides are outdated, or there are hidden
gotchas and I should still get the Contender's pieces?
