they both full up on the markets- though people are now more into the newer sets like war machine etc. but spinners, spriggans, etc are easier to buy that to farm i think- its easier to farm gold doing a chest circuit or farming mats- sell that off and then buy the thing u want.
Agree with those that say to buy Spriggans vs farm it, at least for jewelry. Because of the zone layout you can only do 2 of the dolmens in a rotation so you end up waiting for the WB group to finish the third, so you typically wait 10 minutes to start your next rotation of 2 dolmens. If you join a WB group you can hit 3 WBs, a dolmens, and a Delve.
My result on 2 days of farming the dolmens was 1 purple Spriggans ring. It was worth it to buy the other ring and necklace from a vendor. You can get minor body pieces relatively cheaply off vendors as well. I'm not going to try and spend months grinding for a sharpened bow and daggers so I'll just use Spriggans jewelry and 2 body pieces for the set and use Hunding's weapons.
I always find it faster and more efficient to farm chests than either dolmens or world bosses. With harvestmap add on, its pretty easy. That being said, it will still take you forever to find whatever sharpened weapon you are after.

Where is the end game? You just played it.
Why don't I have 300+ skill points? Because you skipped content along the way.
Where is new content? Sigh.
