End-Game players will probably never pick any of the Accessory Sets since they can farm AQ on a regular basis. The gamble is just not worth it. Weapon Bricks are the main target since it allows for specific grids to build and often involves Hime or Himeless weapons which are overall not so easy to come by.

For Beginners I would not recommend any of the Accessory-Sets since the next problem you gonna encounter is that you cant level them. And by the time you start leveling them, you can clear AQs, so same deal as above. Soul P Set - NO!, AP/BP-Set - NO! These Resources come over time, just be patient.

Gacha Tickets are probably the only thing worth taking since it is quite a bunch of them including SR Tickets, which atleast provide some value. Even the Jewels are not worth the exchange. So if you are not taking a Brick for 10k, then you can take the Tickets and hope for the best.
