How am I suppose to know what is better in Trials, PRIME or SUPERIOR or ?

This has bugged me since the launch of EA. Ive not done the last boss yet so never really thought too much about the rewards but now that my next trial will be 4th I wanna know what is the difference between Superior and Prime?

Why does the game not tell me what is a better chest.. unnecessarily confusing.

Agreed, hope someone would clarify.

Spectrum -> Timeless -> prime royal -> superior royal.

Those are the only chests that really matter in that order.

Past that spam your keys on any random prime chest really.
