Here is a detailed trinket comparison list:

Has a description of each trinket and then below that a tier list for all tank classes (and for Prot Pala separate tier lists for defensive/offensive).
For DPS, assuming same ilvl, Horn+Chrono are the combo for max DPS with Bastion talent. Memento+Chrono seems to be the best combo with First Avenger chosen. Not sure how easily it is to weight for ilvl, don't have a good calculator for it myself.
I typically use 890+socket Horn with 850 Chrono and First Avenger talent for most fights, even though Horn is better with Bastion it doesn't "feel" as good. My Memento is also only 845.
For survivability (and these are a lot more subjective and situational to be fair), the clear winner is DMC, it's nuts.
Grotesque Statuette is solid, especially for single target fights with high tanking uptime, but poor for AOE tanking and fast dying mobs.
The timewalking trinkets are OP despite low ilvl.
I typically run Chrono Shard for the haste feels with Grotesque for ST tanking on hard hitting bosses as a DPS/Mit hybrid option, but that's mostly a preference thing. I haven't used DMC yet because nothing has been hitting me hard enough yet to worry about it.
