There are some very good trinkets from Ulduar Timewalking which competes with Best-in-Slot trinkets!
This week is Ulduar Timewalking and it drops gear at a relatively high item level!
The highlights of Ulduar Timewalking are going to be the trinkets because some of these are overbudget and compete with current raid trinkets!
One of the best highlights is Wrathstone. This trinket is very powerful for classes that have big burst cooldowns as this trinket is On Use Main Stat (Agi/Str). It may not be as powerful as a max level Treacherous Transmitter, but it also doesn't require to do forced movement. For Agi classes, it's comparable to Skardyn's Grace from Grim Batol which is hard to get due to the massive loot pool.
In other words, this is an easy trinket to get that is very close to BiS!
Here are some of the classes that this trinket is very good for:
There are other Int trinkets but the highlight for Int DPS and healers is Living Flame. Compared to the Wrathstone, this isn't as close to BiS due to Spymaster's Web existing, but it is an easier accessible On Use trinket for casters, considering there are no other ones in the pool.
