I prefer vault of glass. The entire raid had a certain feel to it that the other raids can't seem to catch. The Kings fall weapons are the coolest by far but the challenge is literally all "oryx is hard" the vault had atheon, Templar, gorgons. And depended continuously on the shield, so you were familiar with the item, oracles provided a challenge that wasn't just the boss sure we have light eater ogres in the new raid and the light eater knight in the hard mode but still. They have set spawns and just 4. The atheon fight required communication but also one person couldn't sit there and troll your whole team. The weapons had a fun feel to them sure not all of them were designed with perks that complimented the gun like kings fall but overall there were more memorable ones that you can name immediately, fatebringer and vision come to mind immediately for me. So overall I have to agree the vault was a much better raid and for me a lot more enjoyable with a come challenging curve but also providing fair and well worth rewards in the end. Also the exotic doesn't feel like it was built only for the damn raid like the touch of malice does for kings fall.
